Answer:
the answer should be x= -9 over 11
Step-by-step explanation:
Volume = 12 * area of triangular base
area of triangle = 1/2 base * height = 3 * height
height = sqrt(5^2 - 3^2) = 4
area of triangle = 4*3 = 12
Vol of prism = 12*12 = 144 cubic units
Answer:
steps below
Step-by-step explanation:
cos 23° = 6/x
0.92 = 6/x
x = 6/0.92 = 6.52
The conditional and its converse are true, and the biconditional is
