A coat hanger is in the shape of isosceles triangle ABC shown in the figure. Sides AB and BC are congruent. If m=<BAC=22 degrees then m<ABC= ____ degrees

2 Answer

  • Answer:

    136

    Step-by-step explanation:

    22 * 2 = 44

    44 - 180 = 136

  • Using angle sum property, ∠ABC = 136°.

    What is angle sum property?

    Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

    We know that ∠BAC and ∠BCA are 22°.

    Let ∠ABC = x°.

    By angle sum property,

    ∠BAC + ∠BCA + ∠ABC = 180°

    22 + 22 +  ∠ABC = 180°

    ∠ABC = 136°
