Question

in the given figure ab is equal to AC and Angle B is equal to 50 then angle A is​

Answer 1

Answer:

∠MAB = 40°

Step-by-step explanation:

In a ΔABC,

Given,

AB = AC,

∠ABC = 50°

Construction:

Construct AM perpendicular to BC.

⇒∠AMB = 90°

In ΔABC,

Since AB = AC

∠ABC = ∠ACB (Angle opposite to equal sides are always equal)

∠ABC = ∠ACB = 50°

In ΔABM,

∠ABM + ∠BAM + ∠AMB = 180° (Angle sum property of a triangle)

50° + ∠BAM + 90° = 180°

140° + ∠BAM = 180°

∠BAM = 40°

or ∠MAB = 40°

Answer 2

Answer:

Angle C would be 80⁰ by the sum oglf angles in a triangle rule.
