Answer:
(c) ∠ECF and ∠BCF
Step-by-step explanation:
Complementary angles total 90°. Here, 90° angle BCE is divided by ray CF into two complementary angles. They necessarily have a total of 90°.
∠ECF and ∠BCF
4x-7=29 < do you understand how to set that up? Now, the goal is to “get x by itself.”
4x-7=29< now add the 7 to the 29. When you cross an equals sign you change the (+/-) sign of the number you’re moving.
4x= 36< now you will just divide by 4 on both sides. This will give you x by itself on the left side of the equals sign.
x=36/4 which is 9
X=9 :))
Answer:
180 cubic centimeters
Step-by-step explanation:
Volume of prism = base x height
Base of prism = 9*4 = 36
V = bh
V = 36*5 = <u>180 cubic centimeters</u>
