Answer 1

Answer:

hope it helps you

3rd side 15cm

Answer 2

Answer:

15cm

Step-by-step explanation:

Pythagorean theorem

assume the triangle is named abc

let AC=17cm

let BC=8cm

to find AB

=> AC^{2} = AB^{2}  + BC^{2}

=> AB^{2}  = AC^{2}  - BC^{2}

=> AB = \sqrt{AC^{2}  - BC^{2} }

=> AB = \sqrt{17^{2}  - 8^{2} }

=> AB = \sqrt{289-64}

=> AB = \sqrt{225}

=> AB = 15
