Question 1: to solve for y, we will use the Pythagorean theorem a^2 + b^2 = c^2 and c=18 (because it is the hypotenuse) and a=17 (because it is a side) when we plug this in, we get b = sqrt(18^2 - 17^2) = sqrt(35)
To solve for x, we will use SOH CAH TOA. we know the hypotenuse (H = 18) and the adjacent (A = 17). We can use cos(x) = 17/18. We then take the inverse cosine of both sides to get x = 19.18 °
Question 2: we will use this same method to get
y = sqrt(153)
x = 62.73°
