Let →a and →b be two non-zero vectors perpendicular to each other and |→a|=|→b|. If |→a×→b|=|→a|, then the angle between the vectors (→a+→b+(→a×→b)) and →a is equal to:

Let →a and →b be two non-zero vectors perpendicular to each other

1.	Let →a and →b be two non-zero vectors perpendicular to each other and \|→a\|=\|→b\|. If \|→a×→b\|=\|→a\|, then the angle between the vectors (→a+→b+(→a×→b)) and →a is equal to:
Answer» Let $\to a$ and $\to b$ be two non-zero vectors perpendicular to each other and $\| \to a \| = \| \to b \| .$ If $\| \to a \times \to b \| = \| \to a \|$ , then the angle between the vectors $(\to a + \to b + (\to a \times \to b))$ and $\to a$ is equal to:
