Question

1. Find m2K.
4X - 12) 6x-12
130°
a. mZK = 70°
b. mZK = 849
C.mZK = 58°
D.m2K = 729

Answer 1

Answer:

m∠k = 60°

Step-by-step explanation:

• an exterior angle of a triangle is equal to the sum of the opposite interior angles

4x + 2 + 6x - 12 = 130

to find x:

4x + 2 + 6x - 12 = 130

4x + 6x = 130 - 2 + 12

10x = 120

x = 120/10

x = 12

apply the value of x to find the measure of angle K:

k = 6*12 - 12 = 60
