If cos 37 degrees is close to 4/5 which is closest the the measure of op?
alukav5142 [94]
Cos(37)= \frac{adjacent}{hypothenuse} =  \frac{4}{5}
The hypotenuse is 5 unit and the adjacent side to the angle is 4 unit. We can find the other side using Pythagoras theorem

\sqrt{5^{2}- (4^{2})  } = \sqrt{9}=3

Hence the value of sin(37)= \frac{opposite}{hypothenuse}= \frac{3}{5}

Place each of the digits 1, 3, 5, and 6 in the blanks provided to create an expression whose value is 1/10
kompoz [17]

Answer:

\frac{1}{5}\times \frac{3}{6}=\frac{3}{30}

Step-by-step explanation:

From the picture attached,

Multiplication of two fractions gives the result as \frac{1}{10}.

This shows that the denominator of the fractions when multiplied with each other results a number that will be the multiple of 10.

Therefore, from the given numbers,

5 × 6 = 30

Rest two numbers be placed as the numerator of the fractions.

\frac{1}{5}\times \frac{3}{6}=\frac{3}{30}

         =\frac{1}{10}

Therefore, \frac{1}{5}\times \frac{3}{6}=\frac{1}{10} will be the answer.
