Question

Create ∆PQR of a triangle in which Angle Q=30° and Angle R=90° and PQ+QR+PR=11cm

Answer 1

Answer:

given :

triangle PQR

1. angle R=90
2. angle Q=30 degrees
3. PQ+QR+PR =11cm

Step-by-step explanation:

angle R =90 so PQR must be a right angle traingle

from the theorem :

sum of all angles in a triangle=180 degrees

triangle PQR=90+30+x

180=120+x

x=180-120

x=60
