Answer:
Step-by-step explanation:
The square means a 
degree angle.
We know that all the angles in a triangle add to 
degrees. So, we can build an equation for x: 
Combining like terms on the left side gives 
Subtracting 
from both sides gives 
Dividing both sides by 
gives 
Answer:
y = -4x + 17
Step-by-step explanation:
Using the slope intercept formula, we can see the slope of line p is ¼. Since line k is perpendicular to line p it must have a slope that is the negative reciprocal. (-4/1) If we set up the formula y=mx+b, using the given point and a slope of (-4), we can solve for our b or y-intercept. In this case it would be 17.
Answer: z = -13
Step-by-step explanation:
6(10+z+3) =
60 + 6z + 18 =
6z = -60 -18
6z = - 78
z= - 78/6
z = -13
