Answer:

80°

Step-by-step explanation:

The sum of the angles of any triangle must add up to 180°.  If you form a triangle with an angle of 40° and another angle of 60°, the sum of those two angles is 40 + 60 = 100, so the measure of the third angle: 180 - 100 = 80°.

Answer:

Last option

Step-by-step explanation:

I think it would be the last option because when you reflect over the x-axis, the x-axis switched signs.

So, -8 would be 8 , -7 would be 7, and 3 would be negative 3.

Dont think the y-axis value would change..

Hope this helps!

(If this was good..please give brainly.)

The answer is 152 because 102+8= 110 and 6 Times 7 is 42 and 42+110 = 152 so the answer choices are wrong
