Question

one angle of a triangle is65find the remaining two angles if their difference is 20

Answer 1

$\textbf{\large{Answer -}}$

Given,

one angle = 65°

Let the second angle be x.

Then, atq third angle = x - 20

Since, it's a triangle. Therefore the sum of all the three angles will be 180°

Now By triangle sum property,

==> 65 + x + x - 20 = 180

==> 2x = 200 - 65

==> 67.5 °
