A circle has its center at (-4,8), and just touches the y-axis

r = 4 units

Step-by-step explanation:

From the question it is not clear that what you want to ask. But as per me you are interested in finding the radius of the circle.

Since, circle is touching y-axis at has a center (-4, 8) so it's radius will be equal to the x-coordinate.

Here, x - coordinate is - 4

Since radius is a non negative number.

So, r = 4 units

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
