ANSWER
The required angle is

EXPLANATION
Let the angle whose sine is

be

Then

We take the inverse sign of both sides to obtain,

We use our scientific calculator to evaluate and obtain,
Answer:
The surface area of a rectangular prism with length of
15, a width of 9 and a height of 13 is:
894.0000 square units.
not sure
Step-by-step explanation:
To find the surface area, use this rectangular prism surface area
formula:
Surface Area =
[(Length x Width) + (Length x Height) + (Width x Height)] x 2
Example: The surface area of a rectangular prism with length of
3 inches, width of 4 inches, and height of 5 inches:
Surface Area = [(3 x 4) + (3 x 5) + (4 x 5)] x 2
Calculated out this gives a surface area of 94 Square Inches.

A. The equation is true.
67+33=100
70+30=100
100=100 so yes, the equation is equal.
