Answer:
(1)C- Trapezoid
(2)D-20 square feet
Step-by-step explanation:
<u>Question 1</u>
A cross-section of a rectangular pyramid cut perpendicular to the base but not passing through the top will have two parallel sides where one of the sides will be longer. Therefore, the shape which describes the cross-section will be a trapezoid.
<u>Question 2</u>
The base of the Triangle = 5 feet
Height of the Triangle = 8 feet
By applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°
<em><u>Recall:</u></em>
The diagram attached below depicts the problem given.
∅ = x
Opp = 15 ft
Hyp = 50 ft
sin x = 15/50
x =
x = 17.5°
In conclusion, by applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°
