Can someone help? I'll give brainliest if the answer is correct and and if an explanation of how to do this is provided.

= 77°

Step-by-step explanation:

I triangle ACE, BD || AC.... (given)

(corresponding angles)

9x - 5 = 8x + 4

9x - 8x = 5 + 4

x = 9

3x° = 9*3° = 27°

(9x - 5)° = (9*9 - 5)° = (81 - 5)° = 76°

= 180° - (27° + 76°)

(By interior angle sum theorem of a triangle)

= 180° - 103°

= 77°

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

check above link.

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.
