Tamara wants to calculate the height of a tree outside her home. Using her clinometer, she measures the angle from 35 feet away
serg [7]

Answer:

71.32 feet

Step-by-step explanation:

We set up a trigonometric function to get height of tree

Distance ,x = 35 feet away from tree base

Angle = 62⁰ at eye level

Y = tan(angle) * x

= Y = tan(62⁰) x 35

Y = 1.881 x 35

Y = 65.82 feet

We add Tamara's height to the total height of the tree

= 65.82feet + 5.5 feet

= 71.32 feet is the height of the tree

n - 6 = 5n + 10

Combining like terms, we get:

-16 = 4n,

and so n = -4
