HIII! Find Sin D and sin E! Write the answer as a fraction and as a decimal. Round to four decimal places, if necessary! Please help me!

Step-by-step explanation:

Remember that sine is the ratio of the opposite side to its hypotenuse:

For D, the opposite side to D is 28, and the hypotenuse is 53. Therefore:

Or, in decimal form:

Likewise, the side opposite to E is 45, and the hypotenuse is 53. Therefore:

And using a calculator:

step-by-step explanation:

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.
