Pleasee help me!! :(

y=8

Step-by-step explanation:

3y-4 =20

3y = 20+ 4

3y=24

y = 24 / 3

y = 8

Explanation:

The missing angle is M = 60, which you can find by solving L+M+N = 180

From that, we can see that this triangle is equilateral, making sides MN, LN, and LM the same length.

So,

LN = LM

3y - 4 = 20

3y = 20+4

3y = 24

y = 24/3

y = 8

Or we can say:

MN = LM

4y - 12 = 20

4y = 20+12

4y = 32

y = 32/4

y = 8

Or,

MN = LN

4y - 12 = 3y - 4

4y - 3y = -4+12

y = 8

You only need to solve one equation, in any of the three sections mentioned and that's sufficient to find y.

it's

i belive those are the ones that are under 90 degreese.
