Answer:

$\frac{\sqrt{17} }{7}$

Step-by-step explanation:

Using the Pythagorean identity

sin²x + cos²x = 1, then

sinx = $\sqrt{1-cos^2x}$

Note that ( $\frac{4\sqrt{2} }{7}$ )² = $\frac{32}{49}$

sinΘ = $\sqrt{1-(32/49)}$

= $\sqrt{\frac{17}{49} }$ = $\frac{\sqrt{17} }{7}$

Convert the mixed number 1 2/3<br> to an improper fraction.

rodikova [14]

Answer:

5/3

Step-by-step explanation:

An improper fraction is a fraction, not in mixed form, where the numerator (top half) is greater than the denominator (bottom half). Since this fraction is 1 2/3, we already have 1 full and 2/3 full. So, since the 1 is full, it means that in fraction form it equals 3/3.

We can finally add the fractions. $2/3+3/3=5/3$ .
