Answer:

I think that it may be 33

Because, you see 15-9=6

so you do 20-9=11

Then you do 25-9=16

add them all together to get 33 so i think that's the perimeter

I am really not sure if this is correct...i'm kinda bad at stuff like this

Chan receives a bonus from his job. He pays 30% in taxes, gives 30% to charity, and uses another 15% to pay off an old debt. He

charle [14.2K]

Answer:

Chan's Bonus amount was $2400.

Step-by-step explanation:

Let the Total amount receive from bonus be 'x'.

Given:

Chan pays 30% in taxes;

So we can say;

Amount paid in taxes will be equal to 30% of total amount receive

framing in equation form we get;

Amount paid in taxes = $\frac{30}{100}x=0.3x = 0.3x$

Now Given:

Chan pays 30% in Charity;

So we can say;

Amount paid in charity will be equal to 30% of total amount receive.

framing in equation form we get;

Amount paid in Charity = $\frac{30}{100}x=0.3x$

Also Given:

Chan pays 30% in old debts;

So we can say;

Amount paid in Old debts will be equal 30% of total amount receive

framing in equation form we get;

Amount paid in Old debts = $\frac{15}{100}x=0.15x$

Money left with him = $600

Now we can say that Total Amount Receive in bonus will be equal to Amount paid in taxes plus Amount paid in charity plus Amount paid in old debts plus amount left.

framing in equation form we get;

$x=0.3x+0.3x+0.15x+600\\\\x= 0.75x +600\\\\x-0.75x=600\\\\0.25x=600\\\\x=\frac{600}{0.25} = \$2400$

Hence Chan's Bonus amount was $2400.

If m 2X = 34º and m ZZ = 26, what is mZY?<br> OmZY = 26<br> OmZY = 34<br> mZY = 60°

Gre4nikov [31]

Answer:

The measure of the angle Y in given triangle is 120 º.

Step-by-step explanation:

Here, in ΔXYZ

∠X = 34 º , ∠Z = 26 º

By, ANGLE SUM PROPERTY of a Triangle:

Sum of all the interior angles in any given triangle is always 180 º.

⇒ ∠X+ ∠Y + ∠Z = 180 º

or, 34 º + ∠Y + 26 º = 180 º

or, ∠Y = 180 º - 60 º

⇒ ∠Y = 120 º

Hence, the measure of the angle Y in given triangle is 120 º.

Come up with your own system to measure angles. What would you call your unit of measure and how would it work. Describe your sy

aleksley [76]

Answer:

You can try a picture memory method to help students

An example write down notes of what the triangle laws are for angles.

Then interpret them into your picture measurement theory.

Example could be the perpendicular measures of a right angle can be used

to find an area would be the M but as we are finding angles we could use the Big A instead of degrees sign.

We could provide pictures of cars to represent trigonometry

Where back wheels opposite angles and sides from slant are both the unit measure used in Side/sin( A) x sin (B) so this way you label the car wheel angle above of the square boot 'side on' and this angle is A

The B is the one above it linking the slant to find the other measure.

You are asked to design a theme around measuring angles so you need to look at other sin cos and tan calculus to design a picture that can create an image like i've given to find slant.

You need to one that finds angles.

However if you do find a car can help you can always call it square boot as in square root, considering 2/3 of sin cos and tan are square root measures.

Step-by-step explanation:

See the attached ideas and trigonometry

Picture memory Trigonometry

Picture 1. Sunrise Ah side looks for side measure.

The number above is the hypotenuse

A/H = cos ( ) x hyp =base A/H = cos ( ) x hyp = side

Picture 2.Sunrise Soh looks for side measure.

The number above it is the hypotenuse

O/H = sin ( ) =p (for product) take the p x hyp.

Picture 3 Sunrise Toast (Toa) looks for side measure = O/A

Tan ( lower angle ) x base = side

Picture 4 Side of car (Soh) with window as hypotenuse.

Two wheels are the 2 angles given and the back seat is perpendicular to both wheels =

so the triangle structure looks like this /00|7

so you type in 7/sin ( 1st wheel) x (2nd wheel) = hypotenuse.

Both angles given or worked out this is when this is used.

Picture 5 Electric mast looking for slope SIN =S/P = O/A

Angle at top

We have the side at 70 and looking for the slope

Sin( top angle) = p then side/p = hyp

Picture 6

Top angle and base given creates a T this means half both of them before dividing.

To find hypotenuse

Half = 1/2 base / sin (1/2) = hypotenuse

Picture 7

Top angle and base given creates a T this means half both of them before dividing.

To find height =

Half = 1/2 base /Tan 1/2) = Triangle height.

Key checker after pictures are drawn is;

sunrise = low angle x side or low angle x base = hypotenuse.

car = backseat x wheels = hypotenuse always remember when car on side the first

wheel first, second wheel 2nd first in the calculator. The wheels are the 2 angles that

make the car when flipped.

Half = 1/2 base / sin (1/2) = hypotenuse

Half = 1/2 base / tan (1/2) = height

Just take care with top angle and lower angle key words in the drawing descriptions and then the pictures will help.
