Question

If anglea-angleb=60°,then angle a=

Answer 1

Explanation:

angle a - angle b = 60 degree -----(1)

angle a + angle b = 180 degree ----(2)

समीकरण (1) + (2) से --

2 angle a = 240 degree

angle a = 120 degree

समी.(1) से--

120 degree - angle b = 60 degree

angle b = 120 degree - 60 degree

angle b = 60 degree
