What is the measure of the third angle?

SCORPION-xisa [38]

The total amount of degrees in a triangle is 180. All three angles should add up to 180˚

We know that 40+60 = 100

The next step is to do 180-100 to get the other angle.
180-100 = 80

So the measure of the third angle is 80˚

Hope this helps!

(Also if you want to do this in one equation, you would do 40+60+x = 180
40+60+x = 180
100+x = 180 (combine like terms)
x = 80 (Subtract 100 from both sides)

Emma is carpeting 2 perfectly square rooms.

She's wrong. If you have two squares, $S_1$ with side $s_1$ and $S_2$ with side $s_2$ , it's not true that the sum of their areas is equivalent to the area of a square $S_3$ with side $s_3=s_1+s_2$ .
