Answer:
The unknown is 100
Step-by-step explanation:
A straight line is 180 degrees
We have two angles x, and 80
x+80 = 180
x = 180-80
x= 100
Answer:
x= -12
Step-by-step explanation:
move variable to left and change its sign
= 4x - 20 = -68
move constant to the right and change its sign
= 4x = -68 + 20
calucate the sum
= 4x = -48
divide both sides of the equation by 4
x= -12
Answer:
The measure of SWX is 108.
Step-by-step explanation:
TX and QS are not perpendicular.
QRT and TRU are complementary (add to 90) not supplementary (add to 180)
The measure of SWX is 108 because angles on a line add to 180, and RWS is 72. 180 - 72 = 108
