SUMMARY

The discussion centers on solving for the angles in an isosceles triangle with a given angle of 60 degrees. The correct values derived are x = 40 degrees and y = 80 degrees, where y is defined as 2x. The equation used to arrive at these values is 60 + x + 2x = 180, confirming the sum of angles in a triangle equals 180 degrees. The final confirmation of the solution was provided by multiple participants in the discussion.

Hi,

Could someone check that I'm right with this one, or put me right! I've worked the value out as

x=30 and y (2x) = 60. I've come to this as I think it's an isosceles triangle so the base angles would be equal. Am I right?

Thank you!

60 + x + y = 180

if y = 2x ...

60 + x + 2x = 180

try again ...
 
Is it x = 40 and y =80??

Yes, that's correct.
