Question

Hi guys....

Q. Set up an equation in the following cases :

i. In an isosceles triangle, the vertex angle is twice either base angle.( Let the base angles be in degrees. Remember that the sum of angles of a triangle is 180 degrees )


Want the answer with clear explanation....

Pls answer quickly

Answer 1

The equation will be 2b+b+b = 180° .

Let, base angle be "b".

So, vertex angle= 2b

Sum of angles in a triangle= 180 degrees

There are 2 base angles and 1 vertex angle.

So, 

2b+b+b = 180

4b= 180

b=180/4

b=45 degrees.

Therefore,

b=45 degrees

HOPE IT HELPS YOU....

Answer 2

Answer:

Step-by-step explanation:

Let, base angle be "b".

So, vertex angle= 2b

Sum of angles in a triangle= 180 degrees

There are 2 base angles and 1 vertex angle.

So, 

2b+b+b = 180

4b= 180

b=180/4

b=45 degrees.

Therefore,

b=45 degrees
