Question

Find the value of x and y in following figure. Explain your answer​

Answer 1

Answer:

x=40° , y=100°

Step-by-step explanation:

angle CAD = angle BCA (alternative angles)

so, x=40°

because BA=BC (given)

so, angle BAC = angle BCA (angles are equal if their sides are equal)

so, angle BAC =40°

Now, using angle sum property in triangle ABC

BAC + ACB + CBA = 180°

40°+40°+y = 180°

80°+y = 180°

y=180°-80°

y=100°
