Answer:

The lines are parallel.

There is no solution to the system.

Step-by-step explanation:

4x − 9y = 54,

16x − 36y = 208

−16x + 36y = −216

16x − 36y = 208

-------------------------------------------

0 + 0 = −8

0 = −8

Since this is not true, there are no solutions

The lines are parallel

Find the value of x.

kirza4 [7]

Hey there :)

Here we need to use Trigonometry!

The given angle is 61°
The opposite to the angle is 22
So x is the adjacent

The trigonometric ratio that uses opposite and adjacent is tan
( I have uploaded a picture to help you )

tan α = $\frac{opposite}{adjacent}$
tan 61 = $\frac{22}{adj}$
adj = $\frac{22}{tan(61)}$
adj ≈ 12.19 ≈ 12

x = 12
