Answer:
and 
Step-by-step explanation:
At=As+Ar; A=b.h and
, then: At=(x+120)x so
(x+120)x=4500,
Applying cuadratic equation formula:
Supplementary angles need to equal 180 degrees
one angle = t
the other angle = 4 x t or 4t
so we now have t + 4t = 180
4 + 4t = 5t
so we have 5t = 180
divide both sides by 5:
t = 180 /5
t = 36
so angle t = 36 degrees
the other angle = 4 x 36 = 144 degrees
4 divided by 7
Remember a fraction is just a division problem
<h2>
Answer:</h2><h2>
The actual height of the building = 36 feet.</h2>
Step-by-step explanation:
By blue print conversion,
2 inches = 8 feet
Therefore, 1 inch =
= 4 feet
1 inch = 4 feet
The height of the building on the blueprint = 9 inches
The actual height of the building = 9 * 4 = 36 feet.
