Question

If angle of a triangle are in proportion 1:1:2 then find angles ​

Answer 1

Answer:

45 , 45 , 90

Step-by-step explanation:

Let the three angles of the triangle be 1x , 1x and 2x

Now ,

We know that sum of all angles of triangle = 180 degree

Therefore,

1x + 1x +2x = 180

Or, 4x = 180 degree

therefore, x = 45 degree

Hence the angles will be

1x = 1 ×45 = 45 degree

1x = 1 ×45 = 45 degree

2x = 2×45 = 90 degree
