ANSWER
C = 28 degrees
D = 28 degrees
E = 124 degrees
EXPLANATION
We have the three angles of the triangle are given as:
The angles in a triangle sum up to give 180 degrees. This implies that:
C + D + E = 180
=> (x + 3) + (x + 3) +(5x - 1) = 180
Collect like terms:
x + x + 5x + 3 + 3 - 1 = 180
7x + 5 = 180
7x = 180 - 5 = 175
x = 175 / 7
x = 25 degrees
Therefore, the three angles are:
C = 25 + 3 = 28 degrees
D = 25 + 3 = 28 degrees
E = 5(25) - 1 = 125 - 1 = 124 degrees
