Help please find the measurements of angle W

the sum of all the angles = 180

13x-11 + 8x-9 + 30x-4 =180

51x-24 = 180

51x = 204

x=4

w= 8x-9= 8×4-9

= 2e°

23°

Step-by-step explanation:

First, note that the sum of angles in a triangle is 180°.

So, m∠W + m∠B + m∠T = 180°

Substitute the measures.

(8x - 9) + (13x - 11) + (30x - 4) = 180

Simplify.

8x + 13x + 30x - 9 - 11 - 4 = 180

51x - 24 = 180

Add 24 to both sides.

51x = 204

Divide both sides by 51.

x = 4

Then, substitute x = 4 into m∠W

8x - 9 = 8 * 4 - 9 = 32 - 9 = 23°

So, m∠W = 23°

the first one

just id the test.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
