In triangle​ abc, the measure of angle b is 32 degrees more than three times the measure of angle
Yuki888 [10]
Define x:
Let angle a be x.
angle a = x
angle b = 3x + 32
angle c = x + 58

Find x:
Angles in a triangle add up to 180°:
x + 3x + 32 + x + 58 = 180

Combine like terms:
5x + 90 = 180

Take away 90 from both sides:
5x = 90

Divide by 5 on both sides:
x = 18°

Find the angles:
angle a = x = 18°
angle b = 3x + 32 = 3(18) + 32 = 86°
angle c = x + 58 = 18 + 58 = 76°

Answer: The angles are 18°, 86° and 76°.

The diameter of a basketball is approximately 9.5 inches and the diameter of a tennis ball is approximately 2.5 inches .The volu
agasfer [191]

Answer:

The correct answer is the basket ball is 54.87 times bigger in volume than the tennis ball.

Step-by-step explanation:

The diameter of a basketball is approximately given to be 9.5 inches.

The radius of the basket ball is given by \frac{9.5}{2} = 4.75 inches.

The volume of the basket ball is given by = \frac{4}{3} × π × radius^{3} = 449.1012 cubic inches.

The diameter of a tennis ball is approximately given to be 2.5 inches.

The radius of the tennis ball is \frac{2.5}{2} = 1.25 inches.

The volume of the tennis ball is given by = \frac{4}{3} × π × radius^{3} = 8.1845 cubic inches.

Ratio between the volume of the basketball and tennis is given by \frac{449.1011}{8.1845} = 54.87.

Thus the volume of the basket ball is 54.87 times greater than the volume of the tennis ball.
