Answer:
Since the two base angles are congruent (same measure), they are each 70°. If we are given a base angle of say 45°, we know the base angles are congruent (same measure) and the interior angles of any triangle always add to 180°.
degrees
Step-by-step explanation:
Multiply the cone's volume by 3
Cylinder's Volume is
V = pi r ^2(h)
Cone's Volume is
V = 1/3 pi r^2 (h)
the answer is 123 123+156=279.
The quadrilaterals are two congruent isosceles trap ezoids and a kite.
