Answer:
The actual building is 13.3 feet tall.
Step-by-step explanation:
Let the actual height be 'x'.
Given that on a scale drawing with a scale of 1/20, the height of the building is 8 inches, the expression becomes
(1/20) × x = 8
x = 20 × 8 = 160 inches
We know that
Thus,
160 inches = 160/12 ≈ 13.3 feet
Therefore, the actual building is 13.3 feet tall.
so what you would do is 20 x 12 and see what you get and the subtract it from 900 and then see what number would take you to 900

Answer:
x = 114°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus
x + 18° = 132° ( subtract 18° from both sides )
x = 114°
