Find the difference. 5wx²-2wx²
a. 3
b 2wx²
c 3wx²
d 4wx²

Step-by-step explanation:

The illustration above forms a right angle triangle. The right angle triangle formed has an adjacent side of 400 ft which is the distance of the observer from the building . The opposite side of the triangle is the height of the kite flying over the building which is represented as h. The angle of elevation from the observer line of sight is 29°.

Using tangential ratio

tan 29° = opposite/adjacent

tan 29° = h/400

cross multiply

h = 400 tan 29°

h = 400 × 0.55430905145

h = 221.723620581

h ≈ 221.72 ft
