Answer:
f(3) = 71
Step-by-step explanation:
f(x) = 10(x + 5) − 9
f(3) = 10(3 + 5) - 9
f(3) = 10(8) - 9
f(3) = 80 - 9
f(3) = 71
Answer:
51.3 degrees
Step-by-step explanation:
You use the tangent function. You know that tangent of an angle, y, is opposite/adjacent. Set up an equation:
tan(y) = 10/8
You use the inverse tangent (NOT COTANGENT) function, and you get:
y = tan^-1 (10/8)
Type this in your calculator, and you get 51.3 degrees.
