Ahiker descended 320 feet in 40 minutes. find the hiker's average change in elevation per minute. show work

hello.

the answer here is 8.

to find this, simply divide the two numbers.

320/40 = 8.

hope this helped

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
