Plug our values in.

A=(x+6)(x+5)

FOIL-

First: x*x=x^2

In a right triangle, the side opposite a 33 degree angle is 17 units. What is the length of the side adjacent to that angle to t

AnnyKZ [126]

Answer:

The length of the side adjacent to that angle is 26 units

Step-by-step explanation:

We are given

In a right triangle, the side opposite a 33 degree angle is 17 units

Firstly, we will draw diagram

we can use trig

$cot(33)=\frac{x}{17}$

now, we can solve for x

$x=17\times cot(33)$

$x=26.177$

So,

The length of the side adjacent to that angle is 26 units
