<h3>Sin $\theta_{1}=\frac{3\sqrt{21}}{17}$ </h3>

Solution given:

Cos $\theta_{1}=\frac{10}{17}$

$\frac{adjacent}{hypotenuse}=\frac{10}{17}$

equating corresponding value

we get

adjacent=10

hypotenuse=17

perpendicular=x

now

by using Pythagoras law

Hypotenuse ²=perpendicular²+adjacent ²

substituting value

17²=x²+10²

17²-10²=x²

x²=17²-10²

x²=189

doing square root

$\sqrt{x²}=\sqrt{189}$

x= $3\sqrt{21}$

now

In I Quadrant sin angle is positive

Sin $\theta_{1}=\frac{perpendicular}{hypotenuse}$

<h3>Sin $\theta_{1}=\frac{3\sqrt{21}}{17}$ </h3>
