Answer:
14.04º
Step-by-step explanation:
Since it is a right-angle triangle, we can apply the trigonometry identity.
The Tangent rule state that Tan (θ) = Opposite/Adjacent
In the diagram, the opposite (the side that is opposite of the θ) is 5 units.
The adjacent (the side that is along the θ) is 20 units.
Applying the identity,
Tan (θ) = 5/20
θ = 14.04º (nearest hundredth)
Answer:
-2
Step-by-step explanation:
x+3+4=5
x+7=5
subtract 7 on both sides
x=-2
leg = cos(small angle)* hypotenuse
= cos(45)*4 = 2 *Square root of 2 or 2.83cm ( depending on how you need to answer.
This one is a little tricky because of the conversion but .51 cm converts to roughly .2 inches (actually its .200787 but we will round to .2 for ease of math). 4 in/.2in = 20
Therefore the tree is 20 years old.
Footnote 1cm is equal to .3937 inches so it would be .51cm * .3937in = .200787in
