What is 0.542 in a model

0.542=0.500 + 0.040+0.002

         = \frac{5}{10} + \frac{4}{100} +\frac{2}{1000}

        =5 tenth + 4 hundredths + two thousandths

One tenth = \frac{1}{10}

One Hundredth= \frac{1}{100}

One thousandth= \frac{1}{1000}

Step-by-step explanation:

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
