Find $\sin D$ , $\sin E$ , $\cos D$ , and $\cos E$ . Write each answer as a fraction in simplest form. A right-angled triangle D F E, angle F marked right angle, hypotenuse D E marked 15, shortest side D F labeled 9 and second side F E labeled 12.

step-by-step explanation:

their are no angles. sorry cant .

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
