To answer this question we can think Soh Cah Toa. If we are 100 ft from the tree and at an angle of 36 degrees and we want what I call the rise we can us the Toa formula tan(36)=o/100 then manipulate algebraically until we get the following o=tan(36)(100) this give us the height (o) to be 72.65 meters
Answer:
14
Step-by-step explanation:
If he is solving 2 problems per minute and 8 minutes have passed, he has solved
2*8 = 16 problems
There are 30 problems and he has solved 16
30-16 = 14
There are 14 problems left to solve at the start of the 9th minute
Let think the answer is 4*2+5*-7=-27
