Question #4e9e7
1 Answer
tan
Explanation:
A good memory trick for sin, cos, and tan ratios for right angle triangles is "SOH CAH TOA".
SOH:
S = sin
O = opposite
H = hypotenuse
So, the ratio is sin
CAH:
C = cos
A = adjacent
H = hypotenuse
The ratio is cos
TOA:
T = tan
O = opposite
A = adjacent
The ratio is tan
For this particular problem, draw yourself a right angle triangle with the vertical side (height of the tree) being 15 m and the base of the triangle (the shadow) being 15
The two known sides are opposite (15m) and adjacent (15
So, to solve the problem, we simply substitute in our values and solve for
tan
