Answer:
x = 30
since 3x = 90 degrees, then x = 90/3 = 30
Step-by-step explanation:
Wait where’s the x in the equation?
The area of a rectangular shape is given by

Given:
It is given that a gallon of paint covers 400 square feet, and wall is 269 feet long and 4 feet high .
Now the area of wall will be

Since,

So, the ewall requires approx 3 gallon of paint.
X=18 and y=10 because they are both 90degree angles therefore all you have to do is solve the equations: 5x=90 and 9y=90.
Answer:
Height of the building that cast a shadow of 45 meters is 27 meters
Step-by-step explanation:
This is a direct variation and let height of the object represent H and shadow represent S
Hence H∝S
H = KS, where K=constant of proportionality
K = H/S
K = 6/10 = 0.6
Hence height of a building that cast a shadow of 45 meters
H = KS
H = 0.6 × 45 = 27 meters
