Answer:
45°
Step-by-step explanation:
The angle with measure of 9x and the angle with measure of 3x are supplementary
9x + 3x = 180°
12x = 180 divide both sides by 12
x = 15
The angle with measure of 9x and angle a are supplementary as well
9x + a = 180
9×15 + a = 180
135 + a = 180 subtract 135 ftom both sides
a = 45°

The answer is -83.7418
Rounded to: -83.74
Answer:
Step-by-step explanation:
The given expression is
We group the constant terms on the right hand side to obtain;
We square both sides of the equation to remove the square root.
This will simplify to;
Answer:
x= -2
Step-by-step explanation:
-3x+6x+3=x-1
3x-x= -1-3
2x= -4
x= -2
