Question

Calculate the angle x and angle y value in the given figure?​

Answer 1

Answer:-

Consider Δ ABD and Δ ACD

→ BD = CD     (given)

→ AB = AC     (given)

→ AD = AD     (common)

using SSS congruency criteria

Δ ABD ≅ Δ ACD

so,

by CPCT (corresponding parts of congruent triangles )

∠ x = ∠ BAD = 37°

∠ y = ∠ CDA = 70°

Answer 2

Answer:

ZABD = LCD Or BC = ZBAC BDC = ZADB + ZADC and

ZBAC = ZBAR + ZCAD

y + 70 = x 37
