step-by-step explanation:

it's the only multiple of both and the least

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 .

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
