Does someone mind helping me with this answer? Thank you!

Answer 1

Something that you should remember is that the sum of the angles of a triangle add up to 180°.

Since we are given 100° and that the other two angles are equal, we can set up an equation like this:

$180=100+2x$, where x is the 2 angles.

Doing the math, the measure of each unknown angles is 40°.
