Question

Find AB

Round To The Nearest tenth

Answer 1

Answer: 7.7

$\frac{AB}{sinC}=\frac{BC}{sinA}\\\\<=>\frac{AB}{sin44}=\frac{11}{sin82}\\\\<=>AB=\frac{11}{sin82}.sin44\\\\<=>AB = 7.7$

Step-by-step explanation:

Answer 2

sin = opposite / hypotenuse

sin 44° = AB / 11

11 sin 44° = AB

AB = 11 sin 44°

AB = 7.64124......

AB = 7.6 (nearest tenth)
