Answer:
m<YX=60° is a required answer
Answer:
Step-by-step explanation:
X= Fred
56=x+3x
56=4x
Divide both sides by 4
56/4=14
Fred had 14 points and Phil had 42
Check: 14+42=56
Answer:
F
Step-by-step explanation:
The formula for the volume of a square-based pyramid is:
V = a2(h/3), where "V" is equal to volume, "a" is equal to base edge, and "h" is equal to height.
You are given the value of the base edge (a = 6)
If the base edge is equal to (1/2)h, or (1/2)h = 6 then, 2(1/2)h = 2(6). This gives you h = 12.
Now you just plug into your formula:
V = 62(12/3) = 36(4) = 144

Answer:
x = 20
Step-by-step explanation:
4x and 5x are same- side interior angles and sum to 180° , then
4x + 5x = 180
9x = 180 ( divide both sides by 9 )
x = 20
