180=144+3X

X=12

Step-by-step explanation:

angles must add to 180

180=45+80+3X+19

gather like terms

180=144+3X

subtract

36=3X

divide

X=12

X = 12

All triangles add up to 180* so we first need to add the angles

45 + 80 = 125

180 - 125 = 55

We need to have x contribute to the angle being 55*

3 + 19 = 22

55 - 22 = 33

3 x 12 + 19 = 55

x = 12

Step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
