Step-by-step explanation:
plug y value :
10=1/2x+8
1/2x=2
x=4
Answer:
y-2=9(x+3)
Step-by-step explanation:
y-y1=m(x-x1)
y-2=9(x-(-3))
y-2=9(x+3)

Step-by-step explanation:
Answer:
72°
Step-by-step explanation:
So the three angles of a triangle always add up to 180°. This means that

This becomes:

And solves as:

The largest angle has to be the one marked with 24x because it has the largest coefficient and x is a constant.

The measure of the largest angle in the triangle is 72°.
Answer:
540°
Step-by-step explanation:
The sum of the interior angles of a polygon is:
(n-2)*180
where n = number of sides
Here you have :
(5 - 2)*180 = 540°
