See the attached figure to better understand the problem
we know that
in the triangle ABC
tan 61=BC/AC-------> BC=AC*tan 61--------> BC=55*tan 61-----> BC=99.22 ft
tall of the tree =BC+CD-----> 99.22+4.5----> 103.72 ft------> 104 ft
the answer is104 ft
The answer is b because for everything 3 months she pays 22.50 and if you look at the chart on 3 months it has the dot on 22.50
Given, arc QR is congruent to arc LN and arc OP is congruent to arc VW.
And the expressions for each arc in the diagram also given as:
Arc QR = 2x - y, arc LN = 11 , arc OP= 10 and arc VW=5x+y.
Hence, we will get the system of equations as following:
Arc QR = Arc LN
2x - y = 11 ...(1)
Arc OP = Arc VW
5x + y = 10 ...(2)
Next step is to add the two equation to eliminate y so that we can solve the equations for x. Therefore,
2x+5x = 11 + 10
7x = 21
Divide each sides by 7.
So, x= 3
Now plug in x=3 in equation (2) to get the value of y.
5(3) + y = 10
15 + y =10
15 + y - 15 = 10 - 15 Subtracting 15 from each sides.
y = -5
So, x=3 and y =-5
