Perimeter is adding all the outside sides together
1. 7+7+5
14+5= 19 m
3. The dashes mean that the sides are equal so each side is 5
5+5+5+5
10+10= 20cm
Last question.
The sides are 5,3,?,2,1,3,2,?
Look at the top add 5+2 this will give you the length of the whole side
this will let you figure out the bottom missing side
5+2=7
the bottom whole peice will be 7 also so to find the missing peice you will subtract 7-1
the missing piece measure is 6

5,3,7,2,1,3,2,?

Do the same to the right side add 3+2
This will give you the total length of the left and right side (5)
Now subtract 3 from it to find the missing peice
5-3=2
5,3,6,2,1,3,2,2
Now you have all the lengths of the sides
Add them together
5+3+6+2+1+3+2+2
8+6+3+3+4
14+6+4
20+4= 24m
*don't forget to write down in what unit it is measured in!!*
Hope I explained it clearly

From a radar station, the angle of elevation of an approaching airplane is 32.5 degree. The horizontal distance between the plan
denis23 [38]

Answer: 42.21 km

Step-by-step explanation:

We can solve this using trigonometry, since we have the following data:

\theta=32.5\° is the the angle of elevation

d=35.6 km is the horizontal distance between the plane and the radar station

x is the hypotenuse of the right triangle formed between the radar station and the airplane

Now, the trigonometric function that will be used is <u>cosine</u>:

cos\theta=\frac{d}{x} because d is the adjacent side of the right triangle

cos(32.5\°)=\frac{35.6 km}{x}

Finding x:

x=\frac{35.6 km}{cos(32.5\°)}

x=42.21 km

Answer:

<em>MQ = 16 units</em>

Step-by-step explanation:

\frac{x}{14} = \frac{9}{63}

x = \frac{14*9}{63} = 2

<em>MQ</em> = 14 + 2 = <em>16 units</em>

Can you please help me? Thanks!!!!

The answer is 25 degrees.

This is how you solve the equation, first you must know that the straight like ABC=180, DBC is 130, so the remaining amount is 50 degrees, BE is a bisector of ABD which means it splits ABD right down the middle. So ABE+EBD=50 degrees, 25+25=50 since both sides MUST be equal in order for BE to be a bisector of ABD.
