Which is greater? X + -6 or X + -2<br>​
irina1246 [14]
X is just a place holder so it really depends if you know what x is but for right now let’s say it’s 0
Ok so -6 is less than -2 so the larger the negative number is the less it is if that makes sense so the greater number is -2
So x+-2 is greater

Find angle × Find angle y
IrinaVladis [17]

Answer:

Angle x is 64 degrees. Angle y is 128.

Step-by-step explanation:

To find angle x:

In an isosceles triangle, the base angles are always congruent (equal). Since we know that one of the base angles is 64, and x is also a base angle, x is 64 degrees as well.

To find angle y:

Again, in an isosceles triangle, the base angles are always congruent. Since we know that one of the base angles is 26, we know that the other base angle is also 26. Then, to find the last angle (y), you use the triangle angle sum theorem which states that all angles in a triangle add up to 180. To figure out angle y, you do 180-26-26 to get 128. So angle y is 128 degrees.
