Answer:
B
Step-by-step explanation:
The surface area of the prism is 108 square in.
tan(θ) = 0, 0.577, -0.577
3tan³(θ) - tan(θ) = 0
tan(θ)(3tan²(θ) - 1) = 0
tan(θ) = 0
tan²(θ) = ⅓ tan(θ) = +/- sqrt(⅓)
tan(θ) = 0, sqrt(⅓), -sqrt(⅓)
To find θ values, domain is required
Answer: 30 degrees
All angles in a triangle add up to 180 degrees, so you can just write an equation to solve for the measure of angle F. Also, angle C is congruent to angle F because of CPCTC
124 + 26 + F = 180
150 + F = 180
F = 30
The measure of angle F is 30 degrees
we would like to find the inverse of the following function:
to do so substitute y for f(x):
interchange variables:
cancel 9 from both sides:
square both sides:
add 4 in both sides:
divide both sides by 4:
substitute back:
and we're done!
