Find c! please explain the steps and help me find the answer.

34.78

Step-by-step explanation:

using cosine rule

AB^2 = CB^2 + AC^2 -2(CB × AC × COS C)

18^2 = 17^2 + 27^2 -2(27×17×COS C)

324= 289+729- 918COSC

324-289-789= -918COSC

-754= -918COSC

COS C = 754/918

COS C = 0.82135076253

C= arccos(0.82135076253)

C= 34.78(2 dp)

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
