Question

In right angle triangle PQR right angle is at q and pq=6cm,angle rpq =60°. Determine the lengths 9f qr and pr

Answer 1

Answer:

qr = 8 cm

pr = 10 cm

Step-by-step explanation:

according to Pythagoras theorem

hypotenuse^2 - base ^2 = height ^2

in this case pq is the height 6 cm

we should calculate 100 - 64 = 36

and 36 is the square of 6

100 is the square of 10 and 64 is the square of 8

then we get 10^2 - 8^2 = 6^2
