Question

find the value of x and y.​

Answer 1

Step-by-step explanation:

It's an isosceles right angle triangle {Given}

= 90 + x + x = 180                     {Angle Sum Property}

= 90 + 2x = 180

= 2x = 180 - 90

= 2x = 90

= x = 90/2

= x = 45

Value of y will be

= y + 45 = 180                          {Linear Pairs}

= y = 180 - 45

= y = 135

Answer 2

Answer:

Value of x is 45° and y is 135°

Step-by-step explanation:

As shown given 90° and two sides are equal it's a Right angle and an isosceles triangle.

If it's an isosceles triangle the angles opposite to the equal sides are equal.

so, 90° + x + x = 180° (Angle sum property of a triangle)

         90° + 2x = 180°

                  2x = 180° - 90°

                  2x = 90°

                    x = 90° / 2

                       = 45°

∴ x = 45°

so y = ,

45° + y = 180° (linear pair)

        y = 180° - 45°

           = 135°

∴ y = 135°
