Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 3(m∠Y) − 150°. Find m∠Y.

The value of m∠Y is

i think is 40

Step-by-step explanation:

y+s=90

s=3(Y)-150

150=3(y)

y=50

90-50=40

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
