Answer:

50°

Explanation:

Note that all the three angles inside a triangle always add up to 180°.

Here, the three angles we have are ?, 40°, and the right angle at the bottom. Right angles are equal to 90°

So this is what adding all the angles in this triangle looks like: ?+40°+90°, and this is going to equal 180°, so we have:

?+40°+90°=180°

?+130°=180°

?=180°-130°=50°
