Question

What is the measure of the third angle of a triangle if one angle measures 35 degrees and the second angle measures 40 degrees?

Answer 1

Step-by-step explanation: It's important to understand that the sum of the measures of the interior angles of a triangle is always 180 degrees.

So let's first add up the measures of the two angles we know.

So we have 30 + 4 which is 75 degrees.

The missing angle will be equal to 180 minus 75.

So the missing angle measure is 105 degrees.
