Answer:

[tex]AB = 11.3[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Length AB

To do this, we make use of sine law which is represented as:

[tex]\frac{a}{\sin(a)} = \frac{b}{\sin(b)} = \frac{c}{\sin(c)}[/tex]

So, we have:

[tex]\frac{15}{\sin(70)} = \frac{AB}{\sin(45)}[/tex]

Make AB the subject

[tex]AB = \frac{15}{\sin(70)} * \sin(45)[/tex]

[tex]AB = \frac{15}{0.9397} *0.7071[/tex]

[tex]AB = 11.3[/tex]
