Answer» Let Angle 1 be a , Angle2 be b and ANGLE3 be c .Now we know that a = band c = a + 30.Now, we know that the sum of all the angles of a triangle is equal to 180. So, a+b+c= 180So we can substitute b for a and c for a +30. Now, a+a+(a+30)= 180. = 3a+30=180 = 3a= 180-30 =3a=150 =a = 150/3 = a = 50Explanation: PLEASE mark my answer as the brainliest. I hope it helped you! HARRY POTTER IS THE BEST! |
