The vertex angle of an isosceles triangle is 20° less than the sum of the base angles. Which system of equations can be used to
WINSTONCH [101]

The answer to the above question can be explained as under -

We know that, the sum of angles of triangle is 180°.

So, vertex angle plus base angles are equal are equal to 180°.

Let the vertex angle be represented by "v" and base angles be represented by "b".

Thus,  v + b + b = 180°

So,  v + 2b = 180°

Next, the question says, the vertex angle is 20° less than the sum of base angles.

Thus, 2b - 20° = v

<u>Thus, we can conclude that the correct option is A) v + 2b = 180°, 2b - 20° = v</u>

What percent of 65 is 13?
kari74 [83]
So 13/65=x/100 (percent is out of 100) so
if we use a calculator to do 13/65 then we get .2/1
but we want x/100 not x/1 so
multiply top and bottom by 100
.2 times 100=20
1 times 100=100
20/100
20%
