How do I work out angle X?
Thanks
triangles are always 180 degrees, seems like you have the outer corner, which is 116
180-116 is 64
Also it seems like you have a symmetrical triangle, which means x is (180-64)/2
Both angles across the equal sides are themselves equal = x
And using the exterior angle theorem,,,we have that
116 = x + x
116 = 2x divide both sides by 2
58° = x
