Zoom in I think I know this
M∠B = x
m∠A = 4x
x + 4x = 180
5x = 180
x = 180/5
x = 36
m∠B = x = 36°
m∠A = 4x = 4 * 36 = 144°
Answer is <span>b. 144, 36</span>
The answer
the complement of the question is
<span>
Find the interval on the real number line for which the radicand is nonnegative (greater than or equal to zero)</span><span> so that the radical sqrt(8 x - 8) defines a real number. Leave answer in interval notation.
</span>
sqrt(8 x - 8) is definite function if <span>8 x - 8 ≥0, </span>
8 x <span><span> ≥ 8</span> and x </span>≥ 8/ 8 = 1, x <span>≥ 1, so the interval solution is [1, infinity[</span>
