Question

Only answer if you know pls​

Answer 1

m∠A = 115° and m∠C = 50°

Explanation:

We know: the sum of the measures of triangle angles is 180°.

Therefore we have the equation:

`(4x-13)+15+(x+18)=180` combine like terms

`(4x+x)+(-13+15+18)=180`

`5x+20=180` subtract 20 from both sides

`5x=160` divide both sides by 5

`x=32`

`m\angle A=(4x-13)^o\\\\m\angle C=(x+18)^o`

Substitute:

`m\angle A=(4\cdot32-13)^o=(128-13)^o=115^o\\\\m\angle C=(32+18)^o=50^o`
