<M and <N are supplementary and m m=37°. if m<n=(13x)°, what is the value of x and the m<n?
I need to know the equation, what x is, what m<M is, and what m<N is
It is a triangle I need to find the
angles​

Answer:

Step-by-step explanation:

First, you need to know that the word supplementary just means that the angles add up to 180°. So they can't both be in a triangle. Because all three angles in a triangle add up to 180°. But maybe one if them is in the triangle and one is just outside the triangle. Anyway, next we have:

m<M + m<N = 180°

37° + 13x = 180°

Subtract 37 from both sides of the equation.

13x = 143°

Divide both sides by 13.

x = 11

m<M = 37° (given)

m<N = 143° (as calculated above)
