Answer:

x = 12.6

Step-by-step explanation:

Sum of measure of all the arcs of a circle = 360°

m(arc CD) + m(arc CED) = 360°

Since, m(arc CED) = (20x)°

And m(arc CD) = (8x + 6)°

By substituting these measures in teh expression,

(20x)° + (8x + 6)° = 360°

(20x + 8x) + 6 = 360

28x = 360 - 6

28x = 354

x = \frac{354}{28}

x = 12.64

x = 12.6

\boxed{\sf tan\theta=\dfrac{p}{b}}

\\ \sf\longmapsto tan\theta=\dfrac{13}{20}

\\ \sf\longmapsto tan\theta=0.6

\\ \sf\longmapsto tan\theta\approx\dfrac{1}{\sqrt{3}}

\\ \sf\longmapsto tan\theta\approx tan60

\\ \sf\longmapsto \theta\approx 60°

Given: Elmwood St. and Oak Dr. are the same distance. All intersections are perpendicular.
vlabodo [156]

Answer:

The above result is proved with the help of Pythagoras theorem and explained below.

Step-by-step explanation:

Given figure ABCD in which AD=BC and all angles intersect at right angle. Hence, the triangle formed inside ADC and ABC are right angled triangle.

In triangle ADC,

By applying Pythagoras theorem, we get

AC^{2}=AD^{2}+DC^{2}    →  (1)

In triangle ABC,

AC^{2}=AB^{2}+BC^{2}    →  (2)

Now, from eq (1) and (2)

Peach Tree Dr. is the same distance as Sycamore Ln.


AD^{2}+DC^{2} = AB^{2}+BC^{2}

⇒ DC^{2} = AB^{2}              (∵ AD=BC)

⇒ DC=AB                    (∵Distance can never negative)

Therefore, Peach Tree Dr. is the same distance as Sycamore Ln.
