the volume of a sphere can be calculated with the formula v=4/3(pi)(r)^3
Answer:
simplified to 
Step-by-step explanation:
34 I believe because if the shorter side (30) is half the long side (90) it would be 34
Step-by-step explanation:
Apply <u>angle sum of triangle</u>, that means the sum of all interior angles in a triangle is equal to 180°.
So that, (x + 45) + 50° + 90° = 180°.
However when we simply do 45+50+90, the answer is already bigger than 180.
So the question is made wrong.
