Question

Answer Please.......​

Answer 1

b ≈ 1.9

Explanation:

Using the tangent ratio in the right triangle

tan23° =
`(opposite)/(adjacent)` =
`(b)/(4.5)` ( multiply both sides by 4.5 )

4.5 × tan23° = b , then

b ≈ 1.9 ( to the nearest tenth )

Answer 2

7.1

Explanation:

Use the trig ratio tan to find b

4.5 x tan (23) = b = 7.14668887526
