Answer: A
To convert from one unit to another within the metric system usually means moving a decimal point. If you can remember what the prefixes mean, you can convert within the metric system relatively easily by simply multiplying or dividing the number by the value of the prefix.
Multiply 57.6 x 8 = 460. 8 and since you have to convert it to feet you divide by 12 which gets you 38.4 feet
There are 1.5 L in 1,500mL. You can covert it by moving the decimal point over three.
With what number? With all? And why 5. It’s small for this difficult task.
Angle ZYX=180-115=65
in triangle sum of angles =180
so
4k+5+6k+10+65=180
10k+80=180
10k=180+80=260
k=260/10
k=26
