A.) Angle TRS
The other angles do not form straight angles.
Answer:
A
Step-by-step explanation:
Starting with the original equation:

Squaring both sides to remove the root, and expanding the right side:

Multiplying the right side:

Combine like terms:

Factor:
(x+8)(x+1)
If x+8=0, then x= -8
If x+1=0, then x=-1
Smaller rectangular prism:
Width: 5in
Length: 7in
Height: 5in
V= WxLxH
V= 5x7x5
V= 175 in3
Bigger rectangular prism:
Width:11
Length:14
Height:7
V= WxLxH
V=11x14x7
V=1078 in3
ADD THEM ALL TOGETHER:
175 in3 +1078 in3= 1253i n3
Plug in what we know
P = 20 feet, W = 2 feet
20 = 2L + 2(2)
20 = 2L + 4
16 = 2L, L = 8 feet
Convert feet to inches
1 foot = 12 inches
12 * 8 = 96 inches
Solution: 96 inches
