In △DEF, ∠F is a right angle. Find the remaining side and angles. e = 11, f = 15

d = 10.198 or 10.2

Step-by-step explanation:

Remember, the opposite side of the angle is the corresponding length. Meaning the length across ∠F would be f = 15.

If you were to physically draw the triangle, 'f' would be the hypotenuse.

Using Pythagorean Theorem,  or in this case, ,  plug in the given numbers.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
