Ay^2+2ay-3a
a(y^2+2y-3)
a(y-1)(y+3)
A) A triangle can have two congruent angles.
It's called an Isosceles Triangle
The opposite of 17.2 from 0 on a number line would be -17.2.
Find the measure of O?
Line UV is a supplementary line. Line UV is 180 degrees. Angle TU is 30 degrees. Angle WV is 65 degrees. Angle TW (O) is unknown. Add the given angles. 30+65=95 degrees. Subtract the sum of the two angles from 180 degrees. 180-95=85. O is 85 degrees
The correct answer is 18 hope that helped♥
