The measure of 2 base angles on the same side of the trapezoid are 10x + 7 and 6x - 3 respectively. What is the measurement of the larger base angle?

Select one:

a. 16

b. 67

c. 117

d. 147

I'm not sure if understand the question correctly but the way I understand the question:

The sum of angles on one side of trapezoid equals 180.

10x+7 + (6x-3) = 180

10x+7+6x-3=180

16x=176

x=11

Then one angle: 117 the second one 66-3=63

; ) Right I read longer base but the question is larger angle so it is definitely 117 so C is the answer.
