Question

The figure is not drawn to scale. Find the unknown angle.

Answer 1

ThereforeGiven the image, we can find the missing angle using the sum of angles at a point rule.

The sum of angles at a point is known to be 360 degrees.

Therfore,

`\begin{gathered} a^0+315^0=360^0 \\ a^0=360^0-315^0 \\ a^0=45 \end{gathered}`

Therefore, the measure of "a" is

Answer:

`45^0^{}`
