Question

I) Construct a triangle PQR such that |PQ|=8cm,{RPQ=90°{PQR=30°.Measure |RQ|​

Answer 1

6.93 cm

Explanation:

You have a right triangle (90°), so you do as follow:

If I understand correctly, you are looking for the hypotenuse so

`cos(30) = (PQ)/(QR) = (8 cm)/(QR)`

That is equal to
`QR = cos(30)*8 cm = 6.928 cm`
