In δdef, de = 11, ef = 9, and angle e = 140°. which equation correctly uses the law of cosines to solve for the third side? e2 = 112 92 − 2(11)(9)cos(140°) 112 = e2 92 − 2e(9)cos(140°) 92 = e2 112 − 2e(11)cos(140°) e = 11 9 − 2(11)(9)cos(140°)

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.

step-by-step explanation:

where is the question is there is a formula or is there not one
