Second Image: Option D

Third Image: Option C

Fourth Image: Option B

Fifth Image: Option B

Step-by-step explanation:

First Image:

Supplementary angles is two angles whose sum is 180 degrees (straight line)
180 - 47 = 133°
? is an obtuse angle is any angle greater than 90° which checks the answer

Second Image:

A triangle angles adds up to 180°
Two angles are already given
72 + 45 + ? = 180° → 117 + ? = 180° → ? = 63°
? is an acute angle is an angle that measures between 90° and 0°

Third Image:

Supplementary angles is two angles whose sum is 180 degrees (straight line)
180 - 110 = 70°
? is an acute angle is an angle that measures between 90° and 0°

Fourth Image:

Supplementary angles is two angles whose sum is 180 degrees (straight line)
180 - 120 = 60°
we are shown a right angle which = 90°
A triangle adds up to 180°
180 - 90 - 60 = 30
? = 30°
? is an acute angle is an angle that measures between 90° and 0°

Fifth Image:

Supplementary angles is two angles whose sum is 180 degrees (straight line)
180 - 85 = 95°
? is an obtuse angle is any angle greater than 90° which checks the answer
