Answer:

56.6m

Step-by-step explanation:

Using SOH = opp/hyp

Where θ = 45°

Hpy = 80m

Opp = ?

Sin θ = opp/hpy

Sin 45 = opp/ 80

Sin 45 × 80 = opp

0.7071 × 80 = opp

Opp = 56.568

~ 56.6m

Hence the height of the top of the tree is 56.6m

Lady_Fox [76]
Because within each system, units are defined in terms of others in the same system using nice round numbers, but no unit in either system is defined in terms of a unit in the other system. The one exception is the unit of time, and there, the relationship is a nice round number: 1 metric second = 1 imperial second.
