Question

what is the value of x​

Answer 1

Answer:

<x = 100 degrees

Step-by-step explanation:

Since, triangle ABC is an isosceles triangle and AC = BC, by angles opposite to equal sides are equal property, <ABC = <CBA = 50 degrees.

Therefore, by ASP of a triangle, <BCA = 180 - (2 x 50) = 80 degrees.

Now, by linear pair axiom, <ACD ( or <x) = 180 - 80 = 100 degrees.

Thus, <x = 100 degrees.

Answer 2

Step-by-step explanation:

One angle of the triangle is 50°

So the measure of another angles of the triangle are

Let the another two angles be y

We will take both the angles as y because there measure is same

Then, Let it be

50°+y+y= 180° (By angle sum property of a triangle)

=> 50°+2y=180°

=> 2y=180°-50°

=> 2y=130°

=> y= 130°/2

=> y=65°

Hence y is equal to 65°

x will be 130°
