Answer:

Step-by-step explanation:

Use the law of sines.

[tex]\frac{sin A}{a} = \frac{sin B}{b} \\[/tex]

Plug values in.

[tex]\frac{sin88}{17} = \frac{sin42}{b}\\[/tex]

Cross multiply.

[tex]bsin88 = 17sin42\\b = 11.38[/tex]

Hope that helps.

Answer:

11.4 units

Step-by-step explanation:

b/sinB = a/sinA

b/sin(42) = 17/sin(88)

b = sin(42) × 17/sin(88)

b = 11.38215401
