Question

In ∆ABC,angleA=angleC and angle B=Angle A+angle C.Find the measures of the angles of the triangle​

Answer 1

Step-by-step explanation:

when the 2 angles are then it is an isoceles triangle.

here,<A=<C

<B=<A+<C (given)

<B=<A+<A (since, <C=<A)

<B=2A

<A+<B+<C=180° (angle sum property of the triangle)

<A+2<A+<A=180°

4<A=180°

<A=180°/4=45°

<B=2A=2×45°=90°

<C=<A=45°

Answer 2

Answer:

angle A= 45° , B=45°, C=90°
