Answer 2

PQR is the required triangle

Step-by-step explanation:

• draw a line segment PQ = 4,.5 cm
• with P as a center make an angle of 45 degree
• with Q as  a center make an angle of 60 degrees
• The point of intersection of both the rays PX and QY will be the point R

then

we know that the sum of the angles of the triangle is 180°

therefore ,

$\angle P + \angle Q + \angle R = 180^\circ \\\\45 + 60 + \angle R = 180^\circ \\\\\angle R = 180^\circ - 105^\circ \\\\\angle R =75^\circ$

hence , The ,measure of angle R is 75°
