Answer:
7.41, 7.6, 745
Step-by-step explanation:
ANSWER

EXPLANATION
The given equation is

We add the additive inverse of 31 which is -31 to both sides of the equation to get,

Simplify;


The answer is 5/72 you would just divide 5/6 by 12 hope this helped
m∡A = 70º
1) Considering that the Sum of the interior angles within a triangle is always 180º
2) We can write the following, and solve for x
x+80 + x +80 +40 = 180
2x +160 +40 = 180
2x + 200 = 180
2x =180-200
2x= -20
x=-10
3) So since angle A = x +80, we can plug it into that the value of x
m∡A = x +80º
m∡A=-10+80
m∡A = 70º
If G(x) = 39, then
5/2x - 7/2 = 39
Multiplying both sides by 2, we get
5x - 7 = 78
5x = 78 + 7
5x = 85
x = 17
I hope this answer helps!
