Respuesta :
Angle C is 31, Angle A is 30, and Angle B is 119.
Step-by-step explanation:
The measures of each of the angles in triangle ABC are
A = 18
B = 83
C = 79
Calculating the measure of angles
From the question, we are to determine the measure of each of the angles in triangle ABC
From the given information,
The measure of angle B is 29 more than three times the measure of angle A
That is,
B = 3A + 29 ------- (1)
Also, the measure of angle C is 61 more than the measure of angle A
That is,
C = 61 + A --------- (2)
We can also write that
A + B + C = 180 ----- (3) (Sum of angles in a triangles)
Put equations (1) and (2) into equation (3)
A + 3A + 29 + 61 + A = 180
5A + 90 = 180
5A = 180 - 90
5A = 90
A = 90/5
A = 18
Put the value of A into equation (1)
B = 3A + 29
B = 3(18) + 29
B = 54 + 29
B = 83
Put the value of A into equation (2)
C = 61 + A
C = 61 + 18
C = 79
Hence, the measures of each of the angles are
A = 18
B = 83
C = 79
