In which conditions given below a triangle can be drawn:

Angles of triangle are in the ratio 5 : 15 : 16. Find the largest angle 

In a ΔABC, AB = BC, ∠C = x° and ∠B = (2x + 12)°. Then ∠A is equal to:

Let Δ ABC ∼ Δ QPR and \(\rm \frac{ar(\Delta ABC)}{ar(\Delta PQR)}=\frac{1}{16}\). If AB = 12 cm, BC = 6 cm and AC = 9 cm, then QP is equal to:

In the given \(\triangle \)KMN, PQ is parallel to MN. If \(\frac{KP}{PM} = \frac{4}{13}\) and KN = 20.4 cm, find KQ

I is the incentre of ΔABC. If ∠ABC = 70°, ∠BCA = 60°, then the ∠BIC is?

The perimeter of ΔABC and ΔPQR are 24 cm and 40 cm respectively and the length of AB is 5 cm. Find the length of the PQ if ΔABC ~ ΔPQR.

Angle between the internal bisectors of two angles ∠B and ∠C of a ΔABC is 132°, then the value of ∠A is

In Δ ABC, ∠B = 90° and ∠A = 45°. If the length of its hypotenuse is 8 units, then the length of any other side (in units) is

The sides of similar triangles ΔPQR and ΔDEF are in the ratio 5 ∶ 6. If area of ΔPQR is equal to 75 cm², what is the area of ΔDEF?
