Question

In a right angle triangle .triangle PQR if angle p=60degree and angle R=30degree and PR=12 then find

Answer 1

Answer:

Step by step explanation:

Okay, so this is actually really simple. Its based on a property.

It states: The ratio of opposite sides in a 30, 60,90 triangle is 1:2:✓3

Hence the side PR=✓3 X

So PQ, which is opposite to 30°, is 12/✓3

=12/1.73= 6.94 units (approx)

And QR= 12/✓3×2

=24/1.73=Approximately 13.88 units.

Also, we can say that PQ=7 units(approx) an that QR=14 units(approx), to simplify this further.

Hope this helps you.
