Question

Hi, does anyone know the answer to this question? I’m bad at geometry and I’m struggling to answer it.

Answer 1

QT = 16

Explanation:

ΔQRS ~ ΔQRT

In similar triangles, corresponding angles are in same ratio.

`(QS)/(QR)=(QR)/(QT)\\\\(25)/(20)=(20)/(QT)`

Cross multiply,

QT * 25 = 20 * 20

`QT =(20*20)/(25)\\\\QT = 4*4\\\\QT = 16`
