Answer:
r = 13
Step-by-step explanation:
Hypotenuse is the side opposite to 90 degree angle, so hypotenuse is r.
Also, with respect to the angle given, the side "12" is the opposite.
So we have opposite side to angle and we need hypotenuse. Which trigonometric ratio related opposite with hypotenuse? It is SINE.
So we can write:

Rounded to nearest whole number, r = 13
Answer:
In the first term, 5 is a <u><em>coefficient </em></u>of x
In the second term, (3y+ 13) is a <em><u>variable </u></em>which coefficient is 8
In the third term, -1 is a <em><u>constant</u></em>
Step-by-step explanation:
Use the given expression to complete the statements:
5x– 8(3y + 13) – 1
Let's complete the statements, as follows:
In the first term, 5 is a <u><em>coefficient </em></u>of x
In the second term, (3y+ 13) is a <em><u>variable </u></em>which coefficient is 8
In the third term, -1 is a <em><u>constant</u></em>

You can use the Pythagorean theorem a squared plus b squared equals c squared
