By the the sum of the angles in a triangle is equal to 180°. Therefore,
MLA + m B+ m2C = 180º. Using the
(6.)" + 90° +(+6)" = 180" TO
7x = 84 Then
solve for x, first combine like terms to get 7x + 96 = 180. Using the
using the division property of equality, X = 12. To find the measure of angle A use the substitution property to get
m/A = 6(12) Finally, simplifying the expression gets m A 72
