answer:

they form a chain connecting the east-central interior of north america to the atlantic ocean. from the interior to the outlet at the saint lawrence river, water flows from superior to huron and michigan, southward to erie, and finally northward to lake ontario

explanation:

angle a = 40.6°

step-by-step explanation:

for any right angle triangle we know the pythagoras theorem reveals

hypotenuse² = height²+base²

by this formula we will calculate the length of hypotenuse

h² = 6²+7²

⇒ h =√36+49 = √85 = 9.22

now from the given triangle sin a = height/ hypotenuse

                                                sin a = 6/9.22 = 0.651

therefore

so angle a = 40.6°

ok, so basically your gonna start with 350 ok. so there's 60 seconds in a minute so that means you he can go up 10 ft per minute. soo, after 3 minutes he should be at 260 ft after three minutes : )
