Answer:
Step-by-step explanation:
Distribute the 5 into the parentheses (multiply them both by 5)
Subtract the 6.5 from -25.
Divide -31.5 by 15.5.

Answer: option c.
Step-by-step explanation:
You need to remember the identity:
The inverse of the tangent function is arctangent. You need to use this to calculate the angle "R":
You know that you need to find the measure of "R" and (which is the opposite side) and
(which is the adjacent side), you can sustitute values into
Then, you get:
