42
Step-by-step explanation: Just copy the other cone and find half of the diameter to find the radius the cones are congruent.
Answer:
32 × 2 = 64
Step-by-step explanation:
x is being multiplied by 2 so it would be half of 64.

Multiply both sides of the equation by 12

All triangles have a measurement of 180 degrees. Therefore, we can use this information to make an equation to find the value of angle B.
Angle B = 180 - (28 + 36)
Angle B = 180 - 64
Angle B = 116
So, angle B is equal to 116 degrees.
