Answer 1

Answer:

Examine whether the given triangles are congruent or not. Angle are 60 ° and 30° Side is 4cm

Answer 2

Step-by-step explanation:

iven: ΔPQR = ΔSTU (By ASA rule)

∠Q = ∠T = 60° (given)

QR = TU = 4 cm (given)

∠x = 30° (for ASA rule)

Now in ΔSTU,

∠S + ∠T + ∠U = 180° (Angle sum property)

∠y + 60° + ∠x = 180°

∠y + 60° + 30° = 180°

∠y + 90° = 180°

∠y = 180° – 90° = 90°

Hence, x = 30° and y = 90°.
