Question

In an isosceles triangle each base angle is 30 degree greater than the veetical

Answer 1

Hello,

The triangle is isosceles
So,
The base angles will be equal to each other.

Now
The base angles are compared with the vertical angles
So,
Let the vertical angle be x
So,
The base angles will become x+30

Now ,
From angle sum property of triangle we get

x+x+30+x+30 =180
3x+60=180
3x =180-60=120
x=120/3 = 40

So,
The vertical angle is 40 degrees.

The base angles are 40+30 =70 degrees each.

Hope this will be helping you ✌️

Answer 2

Answer:

Vertical angle - 40 degree

Bade angle - 40 + 30 - 70 degree each
