Answer:
98
Step-by-step explanation:
angles 1 and 2 are congruent, the lines in each side of the shape prove this.
another way to solve if you are not sure is to subtract all of the numbers from 360. all quadrilaterals equal 360 degrees, so if you subtract each of the three angles from 360, you will be left with the last angle.
360-120-44-98=98
- Move 4y to the front so it should be 4y=12-3x
- Divide the equation like how I did in the picture above then you should have y=3-3/4x
- Then you switch it to y=-3/4x+3 and that's your answer.
Now for 6x+2y=6
- Move 2y to the front so it looks like 2y=6-6x
- Then you divide the equation by 2 like in the photo above and that should give you y=3-3x
- Finally you switch the equation to y=-3x+3 because we are using the Slope Intercept Form. (Y=mx+b). That's your answer.
Sorry if my handwriting is bad.
24 ÷ (12-4) = 3
A and C also equal 3
Remember the order of operations! makes all the difference!
PEMDAS = (working left to right) parentheses, exponents, division/multiplication, addition/subtraction
