Answer:
y = 17
x = 17
Step-by-step explanation:
If ∠DEF is 42°, that means ∠ABC is also 42°.
We all know that a triangle's total degrees, whether it is equilateral triangle or an scalene triangle, its total degrees will always be 180°.
A. Finding the value of y:
∠ACB = 180 - ∠ABC + ∠BAC
= 180 - 42 + 87
= 180 - 129
= 51
51 divided by 3 is 17.
B. Finding the value of x:
But how do we find the value of x?
87 - 2 = 5x + 2 - 2
85 ÷ 5 = 5x ÷ 5
17 = x
