Question

Construct a ΔPQR in which m∠P = 60° and m∠Q = 30°, QR = 4.8 cm.

Answer 1

Step-by-step explanation:

this is the construction

Answer 2

$\huge{\colorbox{pink}{ Answer }}$

(1) Draw a line PQ = 6 cm.

(2) Using compass taking P as centre draw an angle ∠P = 60°.

(3) Using compass taking Q as a centre draw an angle ∠Q = 30°.

(4) PS and QT intersect each other R.

(5) ∆ RPQ is the required triangle.

On measuring; ∠R = 90°, length of PR = 3 cm.
