Answer 2

Answer:

We know that the sum of the angles of a triangle is 180o.

∴ ∠PQR + ∠QRP + ∠RPQ = 180o

= 105o+ 40o+ ∠RPQ = 180o

= 145o + ∠RPQ = 180o

= ∠RPQ = 180o– 1450

= ∠RPQ = 35o

Hence, the measures of ∠RPQ is 35o.

Steps of construction:

1. Draw a line segment PQ = 5 cm.

2. At point P, draw a ray L to making an angle of 105o i.e. ∠LPQ = 35o.

3. At point Q, draw a ray M to making an angle of 40o i.e. ∠MQP = 105o.

4. Now the two rays PL and QM intersect at the point R.

Then, ΔPQR is the required triangle
