Answer:

541.4 m²

Explanation:

Step 1: find m < V

V = 180 - (50+63) (sum of the angles in ∆)

V = 67

Step 2: find side length of XW using the law of sines


(XW)/(sin(V)) = (XV)/(sin(W))

Where,

V = 67°

W = 63°

XV = 37 m

XW


(XW)/(sin(67)) = (37)/(sin(63))

Multiply both sides by sin(67) to solve for XW


(XW)/(sin(67))*sin(67) = (37)/(sin(63))*sin(67)


XW = (37*sin(67))/(sin(63))


XW = 38.2 m (to nearest tenth)

Step 3: find the area using the formula, ½*XW*XV*sin(X)

area = ½*38.2*37*sin(50)

Area = 541.4 m² (rounded to the nearest tenth.
