Question

In the figure alongside, PQRS is a rectangle. If angle PQT= 30 degree, SR=2√3 cm and angle QTR=90 degree, find the measurement of QR.​

Answer 1

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
