Find the length of AC
Give your answer to 1 decimal place

We will use tangent here as we are finding the opposite with the adjacent given.
So we can simply just put this into a calculator:
tan(68°) × 7 cm = AC
tan(68°) × 7 cm = 17.3 cm
Answer:
AC ≈ 17.3 cm
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan68° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{AC}{7}[/tex] ( multiply both sides by 7 )
7 × tan68° = AC , then
AC ≈ 17.3 cm ( to 1 dec. place )
