Step-by-step explanation:
d^3=d*d*d=10*10*10=1000
450=c*1000
450/1000=c
9/20=c
solved by a system of equations in two variables.
Answer:
x = 29
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
x + 2x + 2 + 3x + 4 = 180, that is
6x + 6 = 180 ( subtract 6 from both sides )
6x = 174 ( divide both sides by 6 )
x = 29
