Step 1
We have: - AD = 30 m - CD = 80 m - ∠BAC = 30° (Note: This angle is not directly in triangle ACD, but it is given for the problem context.) Show more…

The figure shows two adjacent triangular fields ABC and ACD where AD = 30 m, CD = 80 m, and BC = 50 m. ∠ADC = 60° and ∠BAC = 30°. Give answers to the nearest tenth. Using triangle ACD, calculate the length AC. Calculate the size of ∠ABC. 5. Given v = <3, -4> and w = <5, 12>, find the angle between the vectors. Give the answer to the nearest tenth of a degree.

In a triangular-shaped lot ABC, the two sides and the included angle are: CA = 90.95 m, BC = 73.80 m, and angle C = 43°15'. Determine the length of the remaining side AB (10 pts) and the area of the triangular lot (5 pts).
