Supplementary angles add up to 180°
x = greater supplementary angle
x - 118 = lesser angle
x + (x - 118) = 180
2x - 118 = 180
2x = 298
x = 149
x - 118
149 - 118 = 31
the angles are 31° and 149°
The sum of the sides of a quadrilateral is equal to 360º.
x= 4th angle measurement
We have the following equation:
90+156+28+x=360
x=360-90-156-28
x=86
Answer: the size of the 4th angle would be 86º.
The range would be the number-
-6x -(3x)
Pretend that there is a -1 in front of the bracket
-6x-1(3x)
mutiply the bracket by -1
(-1)(3x)= -3x
-6x-3x= -9x
Answer: -9x
