Since both triangles are congruent the angles are also congruent. P the measure we are trying to find is congruent to M since they’re equal it should look like this
5x-19 = 3x+20.4
5x = 3x+ 39.4
2x = 39.4
X= 19.7
to find the measure of angle P plug in X to its equation so
Simplify this and you get 1.5. You can then move the decimal space two spaces to the right to get 150%
