Step-by-step explanation:

Alright so for this one they want us to find the x values of angle 3 and angle 5 and those 2 angles happen to be supplementary meaning that the two angles will add up to equal 180. So to setup the equation we do

180 = 5x+10+3x+10

step 1 combine like terms ( 5x +3x and 10 + 10)

180 = 8x +20

step 2 subtract each side by 20

160 = 8x

step 3 divide each side by 8

x=20

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
