Answer:
25 questions
Step-by-step explanation:
At a math competition 2 students can answer 40 questions in 1 hour.
Therefore, 1 student can answer in 1 hour =
= 20 questions
5 students can answer in 1 hour = 20 × 5 = 100 questions
60 minutes = 1 hour
15 minutes = = 0.25 hours
5 students can answer in 0.25 hours = 100 × 0.25
= 25 questions
5 students could answer 25 questions in 15 minutes.
Calculation of x:
we can see that
x is hypotenuse

opposite=8
adjacent=10
Calculation of z:
we know that sum of all angles of any triangle is 180
