Question

In Triangle F G H, what is the measure of Angle H?

Triangle F G H. Angle F is 43 degrees, angle G is x degrees, angle H is (x minus 1) degrees.
42 degrees
43 degrees
68 degrees
69 degrees

Answer 1

Let x = measure of angle G. Then angle H = x − 1 and angle F = 43.

Sum of angles: 43 + x + (x − 1) = 180
2x + 42 = 180 → 2x = 138 → x = 69

Thus angle H = x − 1 = 69 − 1 = 68 degrees.
