` q / 50 = 60.5 / q`

Q 41 to 50

Construct a triangle P Q R with side Q R=7c m , P Q=6c m and /_P Q R=60o . Then construct another triangle whose sides are 3//5 of the corresponding sides of P Q R .

Q. 46 to 60

In a quadrilateral PQRS, angle P = 50°, angle Q = 50°, angle R = 60°. Find angle S. Is this quadrilateral convex or concave?

In Fig. 10.67, O Q : P Q=3:4 and perimeter of P O Q=60 c m . Determine P Q ,\ Q R and O P . (FIGURE)

If P = -15 and Q = 5 find (P-Q) ÷ (P+Q).
