To find the missing angle in the given image, we start by noting that the problem shows a right angle (which is 90°) and an additional angle of 43°.

In any right triangle, the sum of the three angles is always 180°.

Given:

• One angle is 90° (the right angle).
• Another angle is 43°.

The missing angle $\theta$ can be calculated as:

$\theta = 180^\circ - 90^\circ - 43^\circ$

$\theta = 47^\circ$

So, the missing angle is 47°.
