Answer:
I believe its 8
Step-by-step explanation:
9 + 10 + 13 + 2 +6 = 40 / 5 = 8
X/6.2=-2.1
multiply both sides by 6.2
x=-13.02
A^2+b^2=c^2 so c^2=12^2+16^2 which then simplifies to c^2=144+256 then simplify that to c^2=400. After that take the square root of c^2 and the square root of 400. So your answer is c=20
Angle C is Equal to 84 as well as angle A.
