Simplify brackets
10x - 4 = 8x + 14
Add 4 to both sides
10x = 8x + 14 + 4
Simplify 8x + 14 + 4 to 8x + 18
10x = 8x + 18
Subtract 8x from both sides
10x - 8x = 18
Simplify 10x - 8x to 2x
2x = 18
Divide both sides by 2
x = 18/2
Simplify 18/2 to 9
<u>x = 9</u>
Answer:
x ≈ 34.9
Step-by-step explanation:
Using the sine ratio in the right triangle
sin35° = 
= 
Multiply both sides by x
x × sin35° = 20 ( divide both sides by sin35° )
x= 
≈ 34.9 ( to the nearest tenth )
Answer:
