Step-by-step explanation:
Solution:
Step 1 : Draw a line segment QR = 4.4 cm
Step 2 : Draw an angle of 75° using Protractor at Q on QR
Step 3 : Draw an angle of 30° at R on QR using protractor
Step 4 : Angle drawn in Step 2 & Step 3 intersect at P
Triangle PQR is constructed where QR = 4.4 cm ∠R=30° and ∠Q=75
°
Measure using ruler PR & PQ
PR ≈ 4.4 cm
PQ ≈ 2.3 cm
