Answer: Choice C) 115 degrees
--------------------------------
Explanation:
The three angles are 42, 73 and 65 degrees. Let's call them x,y, and z respectively
x = 42
y = 73
z = 65
To find an exterior angle for x, we subtract the given angle x from 180
180-x = 180-42 = 138
The exterior angle adjacent to angle x is 138 degrees. This isn't listed so we move on
Do the same for y
180-y = 180-73 = 107
This isn't listed either. So we move on
Repeat for angle z
180-z = 180-65 = 115
This is listed as choice C. That's why choice C is the answer
The correct answer would be 20 dollars I believe but that's what I believe you may have a different answer then what I got.
Answer:
x = 22
Step-by-step explanation:
∠VSR and ∠SRU are same- side interior angles and are supplementary, thus
5x + 4 + 44 + x = 180, that is
6x + 48 = 180 ( subtract 48 from both sides )
6x = 132 ( divide both sides by 6 )
x = 22
3y + 9x = 12
3y = -9x + 12
y = -3x + 4
If you want function notation you can replace y with f(x)
f(x) = -3x + 4
Answer:
y = mx + b
-1 = 2/5(-3) + b
-1 = -6/5+b
-1 + 6/5 = -6/5 + 6/5 + b
1/5 = b
y = 2/5x + 1/5
Step-by-step explanation:
- write down the slope-intercept form formula
- identify your x and y of the point
- replace x and y by the point
- multiply m and x
- do addition to get b
- write down the equation by replacing m and b with their values
