It might be 90in
Because it’s asking if the prism below
Sec is 1/cos so sec -120 is 1/cos -120 which is -2
A. No
B. No
C. Yes(probably)
D. Yes
(Sorry if these are wrong :’) good luck!)
(area of square) - (area of triangle)
We know the are of a square is equal to s^2, where s is the side length.
While the are of a right angle tringle is 1/2*base*height
Then we have,
s = 10
base = 4
height = 4
(area of square) - (area of triangle)
=> (10^2) - (1/2)(4)(4)
=> 100 - 8
=> 92
Finally we get: 92 in^2
