Answer:
4.9
Step-by-step explanation:
-6x2 = -144q
Divide both sides by -6
-6x2/-6 = -144/-6 q
X2 = 24q
Square root both sides
X = square root of 24q
X =4.9√q

Answer:
C
Step-by-step explanation:
Supplementary angles add up to 180 degrees-
Let x = "the angle"
supplement angle = 2x + 12 // 12 more than twice the measurement of "the angle"
Supplement angle + "the angle" = 180 degrees
(2x + 12) + x = 180 degrees // 2x + 12 is the supplement angle
3x + 12 = 180 // Simplify
3x = 168 // Subtract 12 from both sides
x = 56 degrees // Divide both sides by 3
The measure of the angle is 56° and its supplement is 124°
