If someone could help me that would be great :)

m<K = 90°

m<L = 39°

m<M = 51°

Step-by-step explanation:

This is z right triangle and thd angle of K is 90°

Since the sum of interior angles in a triangle is equal to 180° The sum of other two angles will be 90°

3x + 21 + 2x + 19 = 90 add like terms

5x + 40 = 90

5x = 50

x = 10

m<L is 2x + 19 ➡ 2×10 + 19 = 39°

m<M is 3x + 21 ➡ 3×10 + 21 = 51°

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.
