Answer:
100 degrees
Step-by-step explanation:
30^2+35^2-2*30*35cos80
=42
180-80=100
80 degrees
42^2=30^2+35^2-2(30)(35)cosx
1764=2125-(2100)(cosx)
-361= -2100cosx
-361/-2100=cosx
0.1719047619=cosx
cos^-1x=80.10141556
Round off to the nearest degree=80
ill say the 8 pack
FRACTION: 10 (10 OVER 256)
__
256
3 x 3 is 9, plus 1 is 10
4x4 is 16, and 16² is 256
z = 7
Based on the midsegment theorem of a triangle, the length of the midsegment of the triangle (z) = ½ of the length of the 3rd side of the triangle (14)
Thus:
z = ½(14)
