Hello!
Since (1, -2) is the point of intersection, then it is the solution to the system of equations. Let's test our answer to see if it's correct:
But that's only for the first one, let's test for the second one:
This is how we know that (1, -2) is the solution to the system of equations. Hope I helped! :3

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
