Given that y = 9 cm and 0 = 23°, work out x rounded to 1 DP.<br> у<br> х<br> 00<br> PLEASE HELP

lozanna [386]

Answer:

x ≈ 3.5 cm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin23° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{y}$ = $\frac{x}{9}$ ( multiply both sides by 9 )

9 × sin23° = x , then

x ≈ 3.5 cm ( to 1 dec. place )
