Hey there! :)
Answer:
m∠2 = 135°.
Step-by-step explanation:
∠1 and ∠2 are supplementary angles, meaning that they both sum up to 180°. Therefore:
m∠2 = 180 - m∠1
m∠2 = 180 - 45
m∠2 = 135°.
Assuming its the same temp, use this equation for pounds and minutes then solve:

cross multiply
50(3.5) = 175 minutes
it'll take an 2 hours 55 minutes
Answer:
