Help please and can you try to explain so I get it

9514 1404 393

  ∠2 = 92°

Step-by-step explanation:

The angles marked with expressions in x are "alternate interior" angles, so are congruent.

  -8x +144 = 2x +74

  70 = 10x . . . . . . . . . . add 8x-74 to both sides

  7 = x . . . . . . . . . . . . . divide by 10

The angles adjacent to angle 2 are ...

  2x +74 = 2(7) +74 = 88 . . . . degrees

Angle 2 is the other angle of the linear pair with angle 2x+74 (or angle 1), so is ...

  ∠2 = 180° -88°

  ∠2 = 92°

step-by-step explanation: 4 cause 2+2=4

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.
