the sun hits a 30 foot flagpole at a 60° angle and casts an unobstructed 52 foot shadow. if a building is built 32 feet away, what height will the shadow strike the side of the building? (round to nearest tenth)
a) 11.0 ft
b) 11.5 ft
c) 12.2 ft
d) 12.5 ft

11.5 ft

Step-by-step explanation:

The length of the shadow of the building = length of the shadow - distance of the building

= 52 - 32

= 20

Let the height the shadow strike the side of the building be h

then by similar shape rule

h / 20 = 30 / 52

52h = 30 x 20

52h = 600

h = 600/52

h = 11.53846154

h ≈ 11.5

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

16.80 times .20= 3.36
