What is m∠c?

round the value to the nearest degree.

Step-by-step explanation:

For this exercise you need to use the Inverse Trigonometric function arcsine, which is defined as the inverse function of the sine.

Then, to find an angle α, this is:

In this case, you can identify that:

Then, substituting values into and evaluating, you get that the measure of the angle "C" to the nearest degree, is:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

answer is 144
