Answer:
∠RUP is 135°
Step-by-step explanation:
First find the angle of QUR
QUS is 90 so you just subtract 45 from 90 and you get 45
QUP is also 90. Add 45 to it this time: 135
Answer: I think it’s 4
Step-by-step explanation:
Because by using a scale factor of 4 and 5 to simplify is 2
Area of base = 9pi
curve surface area = 3*pi*15=45pi
total area 54pi
i guess the n here represents pi the answer would just be a since its the most relevant
