Question

Solve for the value of t.

Answer 1

12

Explanation:

180-91 = 89 (supplementary angle)

(8t-7)=89

8t=96

96\8 = 12

T = 12

Answer 2

t = 12

Explanation:

sum of angles on a straight line = 180 degrees

Therefore:

(8t - 7) + 91 = 180

8t + 84 = 180

8t = 180 - 84

8t = 96

t = 12

Thus t is equal to 12
