Answer 2

Answer:

1. angle s=90°
2. angle t=45°

Step-by-step explanation:

therefore angle r=45°

RT=12cm

angle t=angle r

therefore , RS=ST (equal angles are equal sides)

let RS=ST=x

by Pythagoras theorem,

$1 {2}^{2} = {x}^{2} + {x}^{2}$

144=2x**2

x**2=72

therefore x=✓72

answer is RS=ST=✓72
