Answer:
A: 77
Step-by-step explanation:
360 - 109 - 137 - 37 = 77
Answer: 3 · 30= 90
Step-by-step explanation:
yes you are correct
Well, an interior angle plus an exterior angle has to equal 180°. Also, the sum of the interior angles is represented by this formula: [-2 + n]180, whereas the sum of the exterior angles all add up to 360°, and is represented by this formula: 360/n [let "n" represent the number of sides in every polygon].
The choices are equivalent to the expression correct choices are A, C, and D.
The given expression is
x^3 /5

What is the expression?</h3>
The expression consists of numbers and arithmetic operators. It does not contain equality or inequality symbols.
<h3>What is the power rule?</h3>
![a^{\frac{m}{n} =\sqrt[n]{a^m}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%20%3D%5Csqrt%5Bn%5D%7Ba%5Em%7D)
Therefore the above power rule implies that,
![x^{(\frac{3}{5}) }=\sqrt[5]{x^3}](https://tex.z-dn.net/?f=x%5E%7B%28%5Cfrac%7B3%7D%7B5%7D%29%20%7D%3D%5Csqrt%5B5%5D%7Bx%5E3%7D)
Also, we have the power rule
or it can be written as
![x^{\frac{3}{5} =(\sqrt[5]{x})^3](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B3%7D%7B5%7D%20%3D%28%5Csqrt%5B5%5D%7Bx%7D%29%5E3)
The correct choices are A, C, D.

Answer:
C. 24
Step-by-step explanation:
by algebra:
let "?" be x
35/30 = 28 / x (multiply both sides by 30)
35 = (28/x) (30) (multiply both sides by x)
35x = (28)(30)
35x = 840 (divide both sides by 35)
x = 840 / 35
x = 24
