To find the area of the triangle...

Step 1: a = 7 cos 25o; Step 2: ½ x 7 x (7 cos 25o) x sin25o

Step 1: a = 7 sin 25o; Step 2: ½ x 7 x (7 sin 25o) x sin25o

Step 1: b = 7 tan 25o; Step 2: ½ x 7 x (7 tan 25o) x sin25o

Step 1: b = 7 sin 25o; Step 2: ½ x 7 x (7 sin 25o) x sin25o

Which steps below shows the correct way to get the shortest distance from A to BC?

Step 1: Area = ½ x 8 x 12 x sin 89.6o; Step 2: Shortest distance = (Area) ÷ (½ x 8)

Step 1: Area = ½ x 8 x 9 x sin 89.6o; Step 2: Shortest distance = (Area) ÷ (½ x 9)

Step 1: Area = ½ x 8 x 9 x sin 89.6o; Step 2: Shortest distance = (Area) ÷ (½ x 12)

Shortest distance = 9 cos 44.8o
