Web6 apr. 2024 · By the alternate interior angles theorem, x and 20 ∘ are the alternate interior angles. Hence, they are equal. Therefore, ⇒ x = 20 ∘. 2. The two corresponding angles are given to be 9 x + 10 and 64. What is the value of x? Ans: The two given corresponding angles are congruent. 9 x + 10 = 64 ⇒ 9 x = 64 − 10 ⇒ 9 x = 54 ⇒ x = 6 3.
