Since complementary angles add to 90°, (4x - 1) and (5x + 19), also add to 90°.
Thus, lets form an equation:
90 = 5x + 19 + 4x - 1
72 = 9x
x = 9
Thus, the measure of angle B is 64°.
Answer:
The general formula for the total surface area of a right prism is T. S. A. =ph+2B where p represents the perimeter of the base, h the height of the prism and B the area of the base.
Step-by-step explanation:
Answer:
Diameter = 24 mm
Step-by-step explanation:
Volume of a sphere is 4/3 π
First, we solve for radius:
2304π = 4/3π
Multiply both sides by 3
3(2304π) = 4π
Divide both sides by 4π
6912π/4π =
1728 =
Cuberoot both sides
= r
r= 12
Hence, the diameter would be: 2times the radius = 2*12= 24 mm
