Answer 2

`\sf m\angle 1 = 129^\circ`

Explanation:

To find the measure of the exterior angle of a triangle, we can use the fact that the exterior angle is equal to the sum of the two non-adjacent interior angles.

In this case, we're given that
`\sf m\angle 1` is the sum of two angles,
`\sf 67^\circ` and
`\sf 62^\circ`.

`\sf m\angle 1 = 67^\circ + 62^\circ`

Now, we can find the exterior angle by adding these two angles:

`\sf m\angle 1 = 129^\circ`

So, the measure of
`\sf m\angle 1` is
`\sf 129^\circ`.
