The measure is 30° degrees
3.65 is the correct answer to 0.146 divided by 0.04
1.50x + 6.50y is your algebraic expression.
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°.
