Answer:
x = 20; x = 8
Explanation:
Because 62 and 2 + 3x are opposite angles, they are equal to each other due to geometric rules. Therefore, 62 = 3x + 2 and then 3x = 60. Dividing both sides by 3, we get x = 20 for problem 21.
40 and 6x + 2 are complementary, meaning they add up to 90 degrees. We can set up 40 + (6x + 2) = 90. Simplifying, 6x + 42 = 90 and then 6x = 48. 48 divided by 6 is 8, so x = 8 for problem 22.
