Answer:
(A) if 105° angle and angle 2 are alternate exterior angle, angle 2 must measure 105°. angle 1 and 2 are supplementary angles, the angle 1 must measure 75°
(B) if 105° angle and angle 2 are corresponding angles, angle 2 must measure 105°. angle 1 and 2 are supplementary angles, the angle 1 must measure 75°
Step-by-step explanation:
A. supplementary angle are angles on a straight line which measure 180°
Hence, angle 1 + 105° = 180°
thus, angle 1 = 180° - 105° = 75°
(B) the calculation at A. above is applicable to B.
Answer:
Step-by-step explanation:
Divide 3 on both sides:
Add 1 to both sides:
Multiply by 7 on both sides:
If we take 140 to be the 100%, what is 35 off of it in percentage anyway?
