Question

Help plz I don't understand ​

Answer 1

Answer:

AB ≈ 9.11

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan44° = $\frac{opposite}{adjacent}$ = $\frac{AC}{AB}$ = $\frac{8.8}{AB}$ ( multiply both sides by AB )

AB × tan44° = 8.8 ( divide both sides by tan44° )

AB = $\frac{8.8}{tan44}$ ≈ 9.11 ( to 3 sf )
