PLEASE HELP!! Find the missing side and round to the nearest tenth.

Hey there!

We have an angle of 51 degrees, and a hypotenuse of 16 units in length.

Thus, because the missing side is adjacent to 51 degrees, we can use Cosine 51= x/16, or Cosine 51 (16)=x=10.01

x=10.0 units.

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
