Answer 1

Hi there!

Since we know that the sum of all 3 measures of a triangle is always equal to 180 degrees, and that supplementary angles are equal to 180 degrees when added, we can solve by first finding the supplement to ?.

75 + 40 + ? = 180
180 - 75 - 40 = ?
105 - 40 = ?
? = 75

Now, we find the actual? .

Since 75 + ? = 180,

180 - 75 = 115
? = 115

So, your answer is 115°.

Hope this helps!
