Find the value of x. Round the length to the nearest tenth

x ≈ 777.9 m

Step-by-step explanation:

The lower right angle = 40° ( alternate angle )

Using the sine ratio in the right triangle

sin40° = = ( multiply both sides by x )

x × sin40° = 500 ( divide both sides by sin40° )

x = ≈ 777.9 m ( to the nearest tenth )

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
