Answer:
C. x = 8 , y = 40
Step-by-step explanation:
since this is an Isosceles triangle 5x = 40° and x = 8
The sum of interior angles in a triangle is equal to 180°
40° + 5x + 2y + 20 = 180° add like terms
5x + 2y = 120
40 + 2y = 120 ➡ 2y = 80 and y = 40
Based on my knowledge, you’d set both equations equal to y, and then set both sides equal to each other then solve.
y=-5+x
y=-2x-4
-5+x=-2x-4
then solve from there
(this could be completely wrong, so don’t only go by my opinion)

Answer:
○ I, II, and III
Step-by-step explanation:
Long explanation short, dividing an expression by 2 is the exact same as multiplying an expression by ½. That is to say, dividing a term is the exact same as multiplying by its multiplicative inverse, so all three of these would qualify.
