Given that y = 3x – 10 and y = -2x -15
(-1 , -13)
substituting equation 1 to the equation 2
Y = 3x – 10
3x – 10 = -2x -15
3x + 2x = -15 + 10
5x = -5
X = -1
Substitute -1
Y = 3(-1) – 10
Y = -13

The central angle of this is 112 degrees. That is CAE is 112 degrees. That being the case, CDE is 90 + 90 + 112 = 292 Tangents make a 90 degree angle with the center of the circle.
