Answer: 23 cups
Step-by-step explanation:
There were 4 groups with 5 people each and all of them ordered a cup of hot chocolate:
= 4 * 5
= 20 cups
Rebecca, Malaki, and Jeffrey each ordered an extra cup of hot chocolate so that's 3 extra cups:
= 20 + 3
= 23 cups
we know its diameter is 12, thus its radius must be half that, or 6.

Answer:
m∠U = 54°
m∠T = 72°
Step-by-step explanation:
The triangle shown is an isosceles triangle. Therefore, the 2 sides and angles that are marked must be congruent:
m∠S = m∠U
m∠S = 54°
m∠U = 54°
All angles in a triangle add up to 180°:
m∠S + m∠U + m∠T = 180°
54° + 54° + m∠T = 180°
108° + m∠T = 180°
m∠T = 72°
