t =
submit answer

Explanation:

Step1: Identify vertical angles

Vertical angles are equal, so \( 91^\circ = (8t - 7)^\circ \).

Step2: Solve for \( t \)

Set up the equation: \( 91 = 8t - 7 \).
Add 7 to both sides: \( 91 + 7 = 8t \) → \( 98 = 8t \).
Divide by 8: \( t = \frac{98}{8} = 12.25 \).

Answer:

\( t = 12.25 \)
