Set up this equation:
4y+7+9y=4=180
Combine like terms
13y+11=180
Subtract 11 from both sides.
13y=169
Divide both sides by 13.
y=132.

If they are supplementary angles, then their sum would be equal to 180

So, 4y+7 + 9y+4 = 180
13y + 11 = 180
13y = 180 - 11
y = 169/13
y = 13

Then, Angle 2 = 9y+4 = 9(13)+4 = 117+4 = 121

In short, Your Answer would be: 121 degrees

Hope this helps!

Is anyone good with triangle inequalities? I provided a picture for the problem.
alisha [4.7K]

Answer:

1 < x < 19

Step-by-step explanation:

Triangle Inequality Theorem

Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:

x + y > z

x + z > y

y + z > x

Combining the above inequalities, and provided y>z, the third size must satisfy:

y - z < x < y + z

We are given the measures y=10, z=9. The third side must satisfy:

10 - 9 < x < 10 + 9

1 < x < 19
