47.7 feet.

Step-by-step explanation:

Please find the attachment.

Let h represent the height of the tree.

We have been given that Melissa is standing 40 ft from a tree. The angle of elevation from where she is standing on the ground to the top of the tree is 50°.

We know that tangent relates opposite side of right triangle with its adjacent side.

Round to nearest tenth:

Therefore, the tree is 47.7 feet tall.

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
