In a right triangle, the value of cos B = 3/5. What is the value of sin B?

ozzi

Answer:

4/5

Step-by-step explanation:

cos B = 3/5

cos Ф = adjacent/hypothesis

hypothesis ² = adjacent² + opposite²

5²= 3²+ o²

25 = 9+o²

25-9=o²

16 = o²

√16 = o = 4

Sin B = opposite/hypothesis = 4/5

Divide and write in simplest form 2 1/7 divided by 1 1/4

Hi!

<h3>To divide a fraction, you multiply by the reciprocal of the second fraction. </h3><h3>First, convert the mixed numbers to fractions, by multiplying the denominator by the whole number and adding that to the numerator. </h3>

---------------

2 * 7 = 14

14 + 1 = 15

15/7

---------------

4 * 1 = 4

4 + 1 = 5

5/4

---------------

<u> $\frac{15}{7} * \frac{4}{5} = \frac{60}{35} (simplify) = 1 \frac{5}{7}$ </u>

<h2>The answer is 1 5/7 </h2>

Hope this helps! :)
