Answer:

x = 3.7

Step-by-step explanation:

By applying sine ratio for the given angle B,

sin(39°) = \frac{\text{Opposite side}}{\text{Hypotenuse}}

sin(39°) = \frac{AD}{AB}

0.6293 = \frac{AD}{7}

AD = 4.41

By applying tangent ratio for the given angle C,

tan(50°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

1.19 = \frac{AD}{x}

1.19 = \frac{4.41}{x}

x = 3.7

What is the volume of a rectangular prism with a length of 7m, a hight of 9m and a width of 11m
vazorg [7]
Hello!

To find the Volume of the Rectangular Prism, you'll need to multiply all of the measurements together. So you'll need to multiply 7, 9, and 11 together.

V=7*9*11

First, you'll need to multiply 7 and 9. Once you've multiplied 9 and 7 together, you should have 63. Now you should multiply 63 and 11 together. Once you've multiplied 63 and 11 together, you should have a Volume of 693

You should have a Volume of 693m³

I hope this helps!
