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°.
Answer:
10 degrees
Step-by-step explanation:
7 - (-3) = 7+3 = 10 degrees
Answer:
12
Step-by-step explanation:
4x - 10 = 34
4x +10 +10
4x = 44
4x/4 = 44/4
x = 11
