Help another math problem

Answer/Step-by-step explanation:

Apply trigonometric ratio to solve for x in all problems given.

1. Reference angle = 29°

Adjacent = x

Hypotenuse = 13 m

Thus:

Multiply both sides by 13

11.4 = x (nearest tenth)

x = 11.4 m

2. Reference angle = 63°

Opp = 18 cm

Hypotenuse = x

Thus:

Multiply both sides by x

Divide both sides by sin(63)

x = 20.2 cm (nearest tenth)

3. Reference angle = 71°

Opp = 14 ft

Adjacent = x

Thus:

Multiply both sides by x

Divide both sides by tan(71)

x = 4.8 ft (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
