Answer:
361/20
Step-by-step explanation:
Well start off by simplifying each rate:
17/15 --> can't be further simplified
68/60 = 34/30 = 17/15
So then, yes these rates are equivalent.
Also, you can divide 17/15 and 68/60 and compare the quotients.
Answer:
∠L = 54°
Step-by-step explanation:
5x + 2x + 3x = 180 (all angles in a triangle add up to 180)
10x = 180
x = 18°
∠L = 3x
sub x = 18
3(18) = 54
∠L = 54°
There are 2 before the decimal point because 3×4=12 and 12 has two digits.
There are 3 after the decimal point because we add together the number of digits after the decimal point in the operands, which is 1 plus 2=3. In all then there are 2+3=5 significant figures.
