Answer:

x = 11

m<H = 39°

Step-by-step explanation:

m<G = 6x - 15

m<H = 3x + 6

complementary angles = angles that add up to 90

6x - 15 + 3x + 6 = 90

9x = 99

x = 11

m<H = 3x + 6, plug in 11 as x

3 * 11 + 6

= 33 + 6

m<H = 39°

Part A

Deffense [45]

Answer: Not safe

Step-by-step explanation:

Let the angle of elevation of the ramp be θ, then:

$\begin{aligned}&\sin \theta=\frac{1.5}{10}=0.15 \\&\theta=\sin ^{-1}(0.15) \approx 8.63^{\circ}\end{aligned}$

But the maximum angle for the ramp cannot exceed 7.1°. The calculated angle of elevation will make it difficult, if not impossible, for motorized wheelchairs to get up the ramp.

Therefore, the ramp at the local library is not safe for motorized wheelchairs

You cannot take the square root of a negative number so the radicals must be greater than or equal to-1.
