Answer:
correct simulations of Tom’s scenario.
Step-by-step explanation:
Since complementary angles add to 90°, (4x - 1) and (5x + 19), also add to 90°.
Thus, lets form an equation:
90 = 5x + 19 + 4x - 1
72 = 9x
x = 9
Thus, the measure of angle B is 64°.
21/30 as a percent would be 70%.
The two angles on top are supplementary angles meaning they should add up to 180
72+3x=180
3x=180-72
3x=108
x=36
