Since we know that the sum of the measures of angles in a triangle is 180°, we can write the equation:
m₁ + m₂ + m₃ = 180°
Substituting the given value of m₂, the equation becomes:
m₁ + 47° + m₃ = 180°
The m 2 = 47°. Use this information and the information on the diagram to answer all of the following parts. There are 6 parts worth 1 point each.
a. Write an equation to solve for the m1.
