C is the awnser to that question
Answer:
Step-by-step explanation:
The tangent is perpendicular to the radius. The given triangle is right if AB is tangent.
Use Pythagorean to verify
- 20² = 16² + 12²
- 400 = 256 + 144
- 400 = 400
Confirmed
Area of a prism would 1/2xBxHxL
If prism B is twice twice the Height, then compared to A the area of B would be..
1/2xBx(2H)xL.. so prism B would have twice the volume of A.
Hope this helps
Answer:
you would calculate angles with a protractor by using degrees.
Step-by-step explanation:
the center would be put at one corner and then u measure the side you want to know the angle of. hope this helped.
∠7 = 59°
∠6 = ∠2 = 36° ( vertical angles )
∠4 = 180° - ∠1 ( straight angle )
∠4 = 180° - 95° = 85°
∠7 = 180° - (85 + 36 )° ( sum of angles in a triangle )
∠7 = 180° - 121° = 59°
