Answer:
1.318m
Explanation:
The set up is a right angled triangle
Horizontal distance is the distance covered by the hurdler = 0.535m =adjacent
Angle of elevation = 67.9°
Height of the hurdler = opposite
Using the SOH CAH TOA identity
Using the TOA identity
Tan67.9° = opp/adj
Tan67.9 = opp/0.535
Opp = 0.535tan67.9°
Opp = 1.318m
Hence the required height is 1.318m
