Question

find the value of x and y in given fig ​

Answer 1

Answer:

x=45° and y=45°

Step-by-step explanation:

as the triangle is isosceles the the angle are also same leaving 90°

then,

90°=2x

x=90°/2

x=45°

for y

now,

90°=2y

y=45°

hence we find the value of x and y

x=y=45°

Answer 2

Answer:

we can see two isosceles triangles in the figure.

let the triangle on top be triangle-1

in triangle -1 teo sides  are equal so base angles will be equal

given the other angle in triangle is 30.

so 30+y+y = 180      [sum of angles in a triangle are equal]

            2y   = 180-30

              y   = 150/2

              y = 75

in triangle -2

this triangle also two sides are equal.

the other angle is 90.

then we can say that 90+x+x = 180    [sum of angles in a triangle are equal]

                                         2x   =180-90

                                            x  = 90/2

                                           x =45
