Step-by-step explanation:
- Angle UQN = Angle QNM, in alternate interior angle relation
- so Angle QNM will be x.
- Now we know that the angles inside a triangle sum up to give 180⁰,that is x+x+42⁰=180⁰
2x+42⁰=180⁰
2x=180⁰- 42⁰
2x= 138⁰
x= 138⁰/2
x= 69⁰
D. because he says a little least and plus two of the other answer choices are negative so use process of elimination and D will be your answer.
Answer:
slope intercept form is : y = mx + b
where m is the slope and b is the y-intercept.
The slope, m = (y' - y)/(x' - x)
Is found using the two pints.
The apostrophe is used to denote the other point, different from point (x,y).
once you have the slope, m for the equation y = mx + b ; use one of the points as (x,y) to solve for b.
Answer:
60
Step-by-step explanation:
2x+5+x-5=180
add the common things
3x=180
divide stuff
x=60
