Given cos theta is equal to - 4/ 7 then we can conclude that theta is in the second and third quadrants. In this case, the other leg is equal to square root of (7^2 - 4^2 ) equal to square root of 33. In this case, sin theta can be equal to +- square root of 33 / 7 and tan theta is equal to +-square root of 33 / 4.
Answer:
x = 32800
Step-by-step explanation:
56 × 328 + 162 × 44 + 166 × 44 - x = 0
18368 + 7128 + 7304 − x = 0
32800 - x = 0
-x = -32800
x = 32800

Answer:
144
Step-by-step explanation:
V=PIr^2h
PI=3
V=3r^2h
r=2 h=12
V=3(2^2)12
V=3(4)12
V=12(12)
V=144in^3
