We can calculate using cosinus method in triangle
c² = a² + b² - 2ab cos c
Plug in the number to the formula
c² = a² + b² - 2ab cos c
c² = 10² + 8² - 2(10)(8) cos 105°
c² = 100 + 64 - 160 cos 105°
c² = 164 - 160 (-0.26)
c² = 164 + 41.6
c² = 205.6
c = √205.6
c =14.34
C is 14.34 unit length
Step-by-step explanation:
percentage of green marbles=
(total green marbles÷ total marbles )×100
7 + 3 + 98
14/21 + /3 the 21 is inside the radical and the 3 is in a radical also
