Answer:
Height of the building = 77 ft.
Step-by-step explanation:
Let the height of the building (AB) = h feet
It's given that height of a woman (ED) = 5 feet 3 inches
≈ 5 feet + ft
≈ 5.25 ft
Length of the shadow (BC) of the building = 55 ft
Length of the shadow (DC) of the woman = 45 in ≈ 3.75 ft
Since, both the triangles ABC and EDC are similar, their corresponding sides will be proportional.
By the property of similar triangles,
h =
h = 77 ft
Therefore, height of the building will be 77 ft.
Answer:
Acute angle
Step-by-step explanation:
Given that m<C = , to find out the type of angle angle C is, evaluate the expression given by substituting x = 13, in the expression.
m<C =
m<C =
m<C =
m<C = 76°
Acute angles are less than 90°.
m<C is less than 90°, therefore it is an acute angle.
