Question

I will give lots of points please help

Answer 1

Part A

Use Pythagorean theorem to confirm the right triangle:

• AB² + BC² = AC²

• 12² + 5² = 13²
• 144 + 25 = 169
• 169 = 169

Confirmed

Part B

The triangles are similar:

• ΔABC ~ ΔRST

Corresponding sides have same ratio:

• AB/RS = AC/RT

Substitute known values and find the missing length:

• 12/24 = 13/RT
• 1/2 = 13/RT
• RT = 13*2
• RT = 26

Answer 2

Answer:

yes it is a right triangle if you look closely at triangle ABC there is a right triangle mark the little square
