<h3>Sin

</h3>
Solution given:
Cos

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

x=
now
In I Quadrant sin angle is positive
Sin
