<u>1</u><u>5</u><u> </u><u>inches</u> is the height of the pyramid
Step-by-step explanation:
The volume of a cube is a³
Given <em>a</em> = 5 inches
→ Volume = a³
= 5³
= 5×5×5
= <u>125 in²</u>
The volume of a pyramid is 
Given a = 5 inches , h = height of pyramid
then,
Hence, the height of pyramid is <u>1</u><u>5</u><u> </u><u>inches</u>
Answer:
(x,y)=(0,-23)
Step-by-step explanation:
The formula is called the “midpoint formula”. It looks like this
m=(x1+x2)/2 , (y1+y2)/2 where m means midpoint. In your case it looks like this.
Answer:
x = 80, y = 122
Step-by-step explanation:
I got this equation by using vertical angles to create a complimentary angle pair (they sum to 90 degrees).
3/4x+2/5x-2=90°,
23/20x - 2=90°,
23/20x = 92°,
92/(23/20)
20/(1/4)
20(4)
= 80.
Since the angles are a linear pair on the left side(they sum to 180 degrees). Just subtract 180 from 3/4x-2 and substitute x into the expression.
180-(3/4(x)-2), 180-3/4(80)+2 = 120+2 = 122
