Answer:
<CFE = 28
<RPQ = 53
Step-by-step explanation:
1)
<CFE + 152 = 180
<CFE = 180 - 152
<CFE = 28
2)
Complementary means the angles add up to 90 so:
<RPQ + 37 = 90
<RPQ = 90 - 37
<RPQ = 53
Answer:
225 cm ^ 3
Step-by-step explanation:
First find the volume of the rectangle that is most horizontal.
L * W * H = 10 * 3 * 3 = 90
Then find the volume of the most vertical rectangle
L * W * H = 15 * 3 * 3 = 135
add them together to get...
225
To convert the angle in radian measure to degree measure, multiply it by 180/π.
The given angle in radian measure is 257π/360 . Multiply it by 180/π to get the angle in degrees.
So,
The angle in degrees = 257π/360 x 180/π = 257/2 = 128.5 degrees
