79 ft

Step-by-step explanation:

Given

The angle of elevation is $45^{\circ}$

Distance of the point from the tree is $79\ ft$

Suppose h is the height of the tree.

$\Rightarrow \dfrac{h}{79}=\tan 45^{\circ}\\\\\Rightarrow h=79\tan 45^{\circ}\quad [\tan 45^{\circ}=1]\\\Rightarrow h=79\ ft$

Thus, the height of the tree is 79 ft

$The angle of elevation to a nearby tree from a point on the ground is measured to be 45^{\circ} ∘ .$

$Smaller\ number: x\\\\ \left \{ {{y=4x+2} \atop {y=2x+8}} \right. \\\\4x+2=2x+8\\\\4x-2x=8-2\\\\2x=6\\\\x=\frac{6}{2}\\\\\boxed{x=3}$
