Question

sum of the angle measures of a triangle is 180° suppose that one angle in a triangle has a degree measure of 4X -3 and another has a degree measure of 6X -6 write an expression for the degree measure of the third angle in the triangle

Answer 1

you would add 4x-3 to 6x-6 and equal it to 180° which is 6x+4x-6-3=180° which is 10x-9=180° then use inverse operation to solve it.

Answer: 18.9
