2L + 2W = perimeter
dividing both sides by 2
L + W = (perimeter / 2)
Length = (perimeter / 2) -Width
Width = (perimeter / 2) -Length
Let the measures of three angles be 2x, 9x, 4x
Sum of the angles of a triangle = 180
2x+9x+4x = 180
15x = 180
x = 180/15 = 12
First angle = 2x = 2*12 = 24°
Second angle = 9x = 9*12 = 108°
Third angle = 4x = 4*12 = 48°
I hope it is helpful:D
312 % of 10.5=(312 / 100) (10.5)=(312*10.5) / 100=3276/100=32.76
or:
312% of 10.5=3.12 (10.5)=32.76
Answer: 312% of 10.5 is 32.76.
I think its the first one
