Answer:
AC ≈ 17.3 cm
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan68° = 
= 
= 
( multiply both sides by 7 )
7 × tan68° = AC , then
AC ≈ 17.3 cm ( to 1 dec. 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
