1. A firefighter is called to rescue a cat caught in a tree. If the firefighter is standing 30
m from the base of the tree and if the angle to the cat is 20'. How high in the tree is
the cat?

10.92m

Step-by-step explanation:

See attached picture for more illustration

Using SOH CAH TOA,

Tan 20° = opposite / adjacent

Tan 20° = x / 30

x = 30 * tan20

x = 10.919m = 10.92m

The height of the tree is 10.92m

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
