If it says 3×8 its like saying 8+8+8=21.
It's just a faster way of adding.

Anything multiplied by 0 is 0.

Anything multiplied by 10 just add a 0 to the end of the number example 10×2=20.

tan∅ = opposite over adjacent

Step-by-step explanation:

Step 1: Define

Angle = 28°

Opposite leg of angle = 8 ft

Adjacent leg of angle = x ft

Step 2: Find x

Substitute: tan28° = 8/x
Multiply x on both sides: xtan28° = 8
Divide tan28° on both sides: x = 8/tan28°
Evaluate: x = 15.0458
Round: x ≈ 15.0 ft
