line a is parallel to line b with transversal t. Use the figure to find the measurement of Angle 7

Answer:
105 deg.
Step-by-step explanation:
Angle 75deg. is a corresponding angle to 6. So angle 6 = 75 degrees. line a and b are parallel transversals so angle 6 and 7 are supplementary making angle 7 = 105 degrees.
