If 7 || m, find the value of x
(9x - 4)' Us 4+ (5x + 16)"

Step-by-step explanation:

9x - 4 + 5x + 16 = 180

14x + 12 = 180

14x = 168

x = 12

Step-by-step explanation:

We know that .

Then by the properties of a transversal cutting a pair of parallel lines, we can write:

The property used here is the Consecutive Angles Property. The two consecutive angles are supplementary.

Now, we can solve for x. Rearrange:

Combine like terms:

Subtract 12 from both sides:

Divide both sides by 14:

So, the value of x is 12.

17.08

correct me if i am wrong.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
