Answer:
x=29
Step-by-step explanation:
180-87=93
93=3x+6
-6 -6
--------------
93=3x
/3 /3
-------------
29=x
x=29
*all angles in a triangle add up to 180. So, 35+52=93. 180-93=87.
C=87
In standard form, slope is always the negative of the x coefficient over the y coefficient.
If you dont want to have that memorized, you can use algebra to get the equation of the line into slope-intercept form (y=mx+b)
Set it equal to y
2x - 5y = 6
2x = 5y + 6
2x - 6 = 5y
(2/5)x - 6/5 = y
Now it is in slope intercept form. In slope intercept form, the coefficient multiplying with x is the slope of the line. Therefore, the slope equals 2/5.
