Answer:
Area and Volume of Similar Solids
Two solids are similar if and only if they are the same type of solid and their corresponding linear measures (radii, heights, base lengths, etc.) are proportional.
Surface Area
Recall that when two shapes are similar, the ratio of the area is the square of the scale factor.
For example, the two rectangles above are similar because their sides are in a ratio of 5:8. The area of the larger rectangle is 8(16)=128 units2 and the area of the smaller rectangle is 5(10)=50 units2. If we compare the areas in a ratio, it is 50:128 = 25:64 = 52:82.
Surface Area Ratio: If two solids are similar with a scale factor of ab, then the surface areas are in a ratio of (ab)2.

Answer:
Question 58: 130.4
Question 59: x = 21
Question: 60: 60
Step-by-step explanation:
Question 58: A bisector cuts something into two equals halfs. Since <ABD is 65.2, you have to multiply it by two to receive your final answer of 130.4.
Question 59: A right angle is equal to 90 degrees. So 90 split into two is 45. you take the 45 and plug it into the equation: 45 = (2x + 3) to find your answer.
45 = 2x + 3
42 = 2x
21 = x
Question 60: A bisector cuts something into two equals halfs. Since <ABE is 30, you have to multiply it by two to receive your final answer of 60.
