Answer:
Explanation:
CORRESPONDING ANGLES :
These are the angles in which one angle is interior to the first line and the second angle is exterior to the second line but both the angels lie on the same side of the transversal.
angle 4 and 2 are corresponding angles
Corresponding angles are equal, so x + 30 = 2x + 15
Subtract x and 15 from both sides
We get 15 = x
Plug in x to angle 4 (2x + 15)
2x = (2 x 15), or 30. 30 + 15 = 45. Angle 4 = 45
