Answer:
b
Step-by-step explanation:
because i know it for a fact.
X= 10 I did it on my calculator so don’t worry :)
Answer:
Step-by-step explanation:
I can barely see enough to do 5 and 6. 7 the diagram is unclear and 9 I can't tell where the letters are. I suggest you darken the lines and make sure the letters for the unknowns are clear. Don't hold the paper: just as the picture was taken the image moved slightly. I don't know what to suggest.
Five
The ray defining a is pointing right at the five. That's my first assumption.
You need to find the interior angle connected to a.
Pentagon exterior angles
The total number of degrees for the exterior angles of a pentagon is 360
<em><u>Supplement of 140 degrees</u></em>
140 + x = 180 because the exterior and interior angles are supplementary
x = 180 - 140
x = 40
<em><u>Find a</u></em>
a + 40 + 60 + 84 + 68 = 360
a + 252 = 360
a = 360 - 252
a = 108
Six
This is really hard to read. Including b, there are three angles that are marked the same
Supplement to 68
180 - 68 = 112
Find b
112 + 43 + x + 89 + x +x = 360
244 + 3x = 360
3x = 116
x = 116/3
x = 38.67
Since b is marked as equal to 1 of the 3 exterior angles that are equal, b = 38.67
That is all I can read.
Answer:
y-intercept = (0, 
).
Step-by-step explanation:
Given the linear equation in standard form, 12x + 13y = 8:
We must transform this equation into slope-intercept form to make it easier to determine the coordinates of the y-intercept.
12x + 13y = 8
Subtract 12x from both sides:
12x + 13y - 12x = - 12x + 8
13y = - 12x + 8
Next, divide both sides of the equation by 13 to solve for y:
or 
Next, to determine the y-intercept, we must set x = 0 (because the y-intercept is the point where the graph of the linear equation crosses the y-axis).
Let x = 0:
Therefore, the value of y when x = 0 is . This is the y-intercept, and its coordinate is (0, ).
