The person that answered this is correct, they just didn't solve it all the way (I give tem a 4/5) But yes, x = 35, now just solve and plug in x. 3 x 35 = 105

105 + 13 = 118 answer is 118

Now double check to make sure x is 35

3 x 35 + 13 = 118

35 - 8 = 27

x = 35

118 + 27 = 145

145 + 35 = 180

so x = 35

and your answer is m<A = 118

Hope this helped, and make sure to drop some thank yous and ratings in the other person's answer

We know that the sum of all angles in a triangle = 180°

Angle (A+B+C) = 180°

or

(3x°+13) + (x°-8) + x° = 180

5x° + 5 = 180°===> 5x° = 175° & x =35°
