Answer:
12 sides and measure of each interior angle is 150...
Answer:
Step-by-step explanation:
x - 3y -15
x = -3
The answer is 9 cubic units
Answer:
Side a = 10.44031
Side b = 10
Side c = 3
Angle ∠A = 90° = 1.5708 rad = π/2
Angle ∠B = 73.301° = 73°18'3" = 1.27934 rad
Angle ∠C = 16.699° = 16°41'57" = 0.29146 rad
