What are the measures of the angles in the triangle? A 60; 60; 60 B 78; 51; 51 (6x + 10º) C 34; 112; 112 D 112; 34; 34 (x + 179) (4x - 349) OA

D

Step-by-step explanation:

x+17 = 4x-34

-3x = -51

x = 17

17+17= 34

The bottom two are equal so 34, 34

A triangle adds up to 180

180- 68 = 112

So the top is 112

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
