Choose all of the following angles that cannot

Mathematics
1 answer:
insens350 [35]2 years ago
4 0

Answer:

Step-by-step explanation:

Answer:

Solution:

(i) 135°

No of sides = n

Each interior angle = 135°

(2n -4) x 90° /n = 135°

180n - 360° = 135n

180n - 135 = 360°

n = 8

Which is not a whole number

Hence, it is possible to have a regular polygon whose interiro angle is 135° .

(ii) 155°

No of sides = n

Select all of the expressions that are undefined. csc(0) sec(0) csc(pi/2) sec(pi/2) csc(pi) sec(pi)
Softa [21]

Answer:

The answer is "undefined, 1, undefined, undefined, and -1".

Step-by-step explanation:

Finding expression:

i) \csc(0) = \ cosec 0^{\circ} \\\\= \frac{1}{sin 0^{\circ}}\\\\= \frac{1}{0} \ \\\\undefined

ii) \csc (\frac{\pi}{2})\\\\= cosec \frac{\pi}{2}\\\\= cosec  \ 90^{\circ}\\\\= \frac{1}{\sin \ 90^{\circ}}\\\\= \frac{1}{1} \\\\=1\\

iii) \sec \frac{\pi}{2} \\\\= sec \ 90^{\circ}\\\\= \frac{1}{\cos 90^{\circ}}\\\\= \frac{1}{0}  \\ undefined

iv) \csc(pi)\\\\= \ cosec (180^{\circ})\\\\=  \frac{1}{\sin 180^{\circ}}\\\\= \frac{1}{0}\\undefined

v) sec (\pi) \\\\=\frac{1}{\cos 180^{\circ}}\\\\= \frac{1}{-1}\\\\= -1

Find the quotient of 7/8 divided by 1/4 by using the procedure. Write your answer as a proper fraction, whole number or mixed nu
Julli [10]

Answer:

7/8 x 4/1

make 1/4 a reciprocal (basically just turning the fraction upside down)

then turn the division sign into a multiplication sign and multiply across:

7/8 x 4/1 = 28/8 = 3 4/8 = 3 1/2

3(-X+4)=7x-8. Yeahhhh...
katovenus [111]

Hey there!☺

Answer:\boxed{x=2}

Explanation:

3(-x+4)=7x-8

Let's start by simplifying both sides. First, we distribute.

(3)(-x)+(3)(4)=7x+-8

-3x+12=7x+-8

-3x+12=7x-8

Now let's subtract 7x from both sides.

-3x+12-7x=7x-8-7x\\-10x+12=-8

Now we will subtract 12 from both sides.

-10x+12-12=-8-12\\-10x=-20

In our last/final step, we will divide both sides by -10.

\frac{-10x}{-10}=\frac{-20}{-10}

Now simplify -20/-10.

-20/-10=2

x=2

Hope this helps!

-25(10-x)=5x+50 <br><br> I don’t understand how to solve this math problem
Tanya [424]

I'm sorry to hear your stuck! Let''s learn how to do this.

Simplify both sides of the equation!

−25(10−x)=5x+50

(−25)(10)+(−25)(−x)=5x+50 - Distribute

−250+25x=5x+50

25x−250=5x+50

Now subtract 5x to each side.

25x−250−5x=5x+50−5x

20x−250=50

Add 250 to both sides. (We need to get x by itself)

20x−250+250=50+250

20x=300

Divide both sides by 20!

You get x = 15.

I'd take notes and look through on how this problem was solved for future references.

Have a good one!
