Answer:

x=128

Step-by-step explanation:

first find the base angles (isosceles triangles have congruent base angles and two congruent legs) so do 180-76=104 then divide by 2 =52. Then to find exterior angle add the top angle (76) to one base angle (52) then you get 128 which is the exterior angle.

For the second one, remember LW=are for fiding the area of the base,
for cone, base=circle, so therfor V=HB/3, and B=circle=pir^2, so V=(1/3)(hpir^2)
h=17
r=6
V=(1/3)(17(3.14)6^2)
V=17(3.14)12
V=640.56
rond tenth
V=640.6

Suppose that the functions p and q are defined as follows.

devlian [24]

P(x) = -x - 1
q(x) = 2x^2 - 2

(q o p)(-4) = 2(-x - 1)^2 - 2
(q o p)(-4) = 2(-x^2 + x + x + 1) - 2
(q o p)(-4) = 2(-x^2 + 2x + 1) - 2
(q o p)(-4) = -2x^2 + 4x + 2 - 2
(q o p)(-4) = -2x^2 + 4x
