A tree is currently 10 feet tall and grows 2 feet per year. Write a formula for the table in slope-intercept form.
f(3) =

How tall, in feet, will the tree be in 15 years?

x = 166

Step-by-step explanation:

the vertex inside the Δ and 97° are adjacent, thus

vertex = 180° - 97° = 83°

The Δ has 2 congruent sides and thus is isosceles, so the base angles are congruent, both 83°

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an external angle of the triangle, thus

x = 83 + 83 = 166
