Okay, so supplementary angles = 180 degrees.
Starting equation : 4y + 7 + 9y + 4 = 180
Combine like terms : 13y + 11 = 180
Subtract 11 from both sides : 13y = 169
Divide 13 from both sides : y = 13
Insert y value into original m<2 equation : 9(13) + 4
Solve : 121 degrees
If you want to check your work, all you have to do is insert y value into original m<1 equation and then add both m<1 and m<2. If they equal 180, your answer is correct.
4(13) + 7 = 59
59 + 121 = 180

Step-by-step explanation:
7. <u>AD</u> and <u>CD</u> are congruent. Each of the triangles are the same in length and shape (both are right triangles). They are the same but are mirrored over the line <u>BD.</u>
8. I have no idea. Sorry.

(3x^2-2x+4)+(5x^2+6x-8) - Combine like terms
8x^2+4x-4
(f+g)(x)=8x^2+4x-4
