-2x • 3x = -6x2 (the 2 is an exponent)
4y • -7y = -28y2 (the 2 is an exponent)
-2x • -7y = 14xy
4y • 3x = 12xy
14xy + 12xy = 26xy
—> -6x2(expo) - 28y2(expo) + 26xy
Check the answer again just to be sure, it’s been a while since I’ve had algebra!
Answer:
120°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 since a pentagon has 5 sides, thus
sum = 180° × 3 = 540°
let x be the measure of the 3 equal angles
Sum the interior angles and equate to 540
112 + 68 + 3x = 540, that is
180 + 3x = 540 ( subtract 180 from both sides )
3x = 360 ( divide both sides by 3 )
x = 120
Hence the measure of each equal interior angle is 120°
The answer to this question is c
A circle is made up of angles totaling 360 degrees. To find the missing measurement, add 90 and 114. This equals 204, then Subtract 204 from 360. 360-204=156. The missing angle measurement is 156 degrees.
