Find the value of x. Round to the nearest degree.
dmitriy555 [2]

Answer:

a. 53

Step-by-step explanation:

The side with length 15 is opposite the right angle, so it is the hypotenuse of the right triangle.

For angle x, the side measuring 12 is the opposite leg.

Our 3 items of interest are: angle, opposite leg, hypotenuse.

The trig ratio that relates the opposite leg to the hypotenuse is the sine ratio.

sin x = opp/hyp

sin x = 12/15

sin x = 0.8

Now we take the inverse sine of 0.8 to find the measure of the angle.

x = sin^(-1) 0.8 = 53 deg

Can someone please help me find the volume?
Mrac [35]

Answer:

C

Step-by-step explanation:

Volume = base * height.

The area of the base = base * height/2

That means the area of the triangular base is 8 * 5.1/2 = 20.4

The height is 9, so the volume is 20.4 * 9.

That means the volume is 183.6, which is C
