Abby used the law of cosines for kmn to solve for k. k2 = 312 + 532 – 2(31)(53)cos(37°) law of cosines: a2 = b2 + c2 – 2bccos(a) what additional information did abby know that is not shown in the diagram? mk = 37° and n = 31 mk = 37° and k = 31 mn = 37° and n = 31 mn = 37° and k = 31

mK = 37° and n = 31

Step-by-step explanation:

its A of ed.

(A) mK = 37° and n = 31 just took the test

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.
