Answer:
a. 30 degrees
b. 60 degrees
c. 105 degrees
Step-by-step explanation:
Angle a is 30 degrees becuase it is congruent to the one right above it
Angle b is 60 degrees because the interior angles of a triangle always add up to 180. We know that angle a is 30 degrees and the angle with the mini square is a right angle, and right angles are always 90 degrees. Based on this information, we can subtract 90 from 180 followed by subtracting 30 from 90, which equals 60. Angle b is 60 degrees
Angle c is 105 degrees because a straight angle is 180 degrees. We know that one angle is 75, so we subtract 75 from 180 to get the difference. The difference is 105 degrees, which is also the measurement of angle c.
Hope this helps!
