Ranjit say that X degree X + 20 degree and X + 70 degree are three angles of an obtuse angle Kangal do you agree with her give reason​

Answer 1

Answer:

Given  :Ranjit say that X degree X + 20 degree and X + 70 degree are three angles of an obtuse angle triangle

To Find : do you agree with her give reason​

Solution :

Since these are the angles of triangle

So, By angle sum property of triangle

$x+x+20+x+70=180$

$3x+90=180$

$3x=180-90$

$3x=90$

x=30

x+20=30+20=50

x+70=30+700=100

Since 100 is an obtuse angle

So, I agree with Ranjit that is  obtuse angle triangle
