Question

Find angle X + angle Y option A 90 degree option B 180 degree option C 70 degree and option the hundred degree find the answer fast please

Answer 1

Answer:

180degree

Step-by-step explanation:

x+y is a sum in angle

means that an angle is a isosceles angled-triangle

In this triangle 2sides are equal and the other side is different

that means,we suppose

Let,

x,x,y are the sides

you know that,

Sum of triangle is 180degree

Since, y is twice x

x+x+y=180degree

=(2x)+y=180

=x+y=180/2

=x+y=90

This value is x=90

Then,

Y=90

X =90

There are two x,

Then, x/2

=90/2

=45

Since,

45+45+90=180 degree
