Answer:
a. 16
Step-by-step explanation:
Triangles = 180 degrees
180 - 80 = 100
100 = (4x - 4) + (0.5x + 32)
4x - 4 + 0.5x + 32 =100
(4x + 0.5x) +(-4 + 32) = 100
4.5x + 28 = 100
4.5x + 28 -28 = 100 - 28
4.5x = 72
4.5x/4.5 = 72/4.5
x = 16
A.
y = 7 - |x| = 7 - 2 = 5
b.
y = x² - 1 = 2² - 1 = 4 - 1 = 3
c.
y = √(x + 14) = √(2 + 14) = √16 = 4
