Answer:56
Step-by-step explanation:do 180-68, then divide by 2(because the x angles are equal to each other.
F(x) = x^2 - 3x - 7
f(-3) = (-3)^ 2 - 3(-3) - 7
f(-3) = 9 + 9 - 7
f(-3) = 18 - 7
f(-3) = 11
Answer: 72
Step-by-step explanation: volume of a pyramid = v= lwh/3
v= 6*6*6/3
v = 216/3
v = 72
Sin404 = sin(360 + 44)
as sin(360 + α) = sinα
= sin44
