Two angles form a linear pair. One angle measures 2
x
and the other angle measures
10
x
. Find the measure of the smaller angle.

30 degrees

Step-by-step explanation:

a linear pair adds up to 180 degrees. therefore, you can compose the equation 2x+10x=180

12x=180

x=15

the smaller angle is 2x, so 2 times 15 is 30

A) 0.5(2) + 80 = 81

B) 83

C) f(4) = 0.5(4) + 80 = 82

g(x) = 2x + 79

Slope: (83-81)/(2-1) = 2

y = 2x + c

When x = 1, y = 81

81 = 2 + c

c = 79

g(x) = 2x + 79

g(4) = 2(4) + 79 = 87

Since 87 > 82,
