Do you understand trigonometry ? (sine, cosine, tangent)
Answer:
Michael (m) practiced 7 hours and Gen (g) practiced 5
Step-by-step explanation:
g+m+2=12
-2 -2
g+m=10
10 divided by 2 is 5
They both practiced free throws for 5 hours. Michael practiced two hours more that Gen. 5+2=7. Therefore, Michael (m) practiced 7 hours and Gen (g) practiced 5.
Cos20=opp/hyp
cos20=19/x
x=19/cos20
10(the number of tests) divided by 5(the amount of weeks)=2. That is 2 tests every week. 2x7 weeks is 14 tests.
Or this could be a trick question and he could have only had tests for 5 weeks.
