Which of the following show two similar triangles?

option b , because

in triangle abc= 60+79+?=180

=139+?=180°

x=180-139

=41°

and if you do the same as I have shown on the first triangle for the 2nd one u will get the answer as 60 degree..

and also one last thing , check whether the triangle are both similar in shape too..

hope this helps!

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
