2 Step-by-step explanation:
in the places there is X you put -3 , -3 squared minus 7 is equal to 9 , 9-7 is equal to 2
Since a is parallel to c and c is perpendicular to b, than a is also perpendicular to b.
perpendicular lines create right angles, so angle 1, 2, 3, 4, 5, 6 .7 & 8 are all right angles.
A right angle = 90 degrees.
Angle 2 = 90 degrees.
