Atree casts a shadow that is 20 feet long. the angle of elevation from the end of the shadow to the top of the tree is 66 degrees. determine the height of the tree to the nearest foot. answer

Height of tree = 45 feet

Step-by-step explanation:

Refer the given figure.

Shadow length of tree, = AB = 20 ft

The angle of elevation from the end of the shadow to the top of the tree is 66 degrees.

∠ABC = 66°

We have

Height of tree = 44.92 feet = 45 feet

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
