Answer:
7.1
Step-by-step explanation:
Use the trig ratio tan to find b
4.5 x tan (23) = b = 7.14668887526
b ≈ 1.9
Using the tangent ratio in the right triangle
tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{b}{4.5}[/tex] ( multiply both sides by 4.5 )
4.5 × tan23° = b , then
b ≈ 1.9 ( to the nearest tenth )
