Guys please help! In triangle CDE, the measure of angle C is 90 degrees, side CD is 15 and DE is 3 more than CE. Find the length
AURORKA [14]
You can calculate it using the law of cosines: c^2=a^2+b^2-2*a*b*cos(C)

your triangle is
CD=15=a
CE=?=b
DE=CE+3=b+3=c
and C=90°

-> insert those values, with c substituted with b+3 to remove c

c^2=a^2+b^2-2*a*b*cos(C)
(b+3)^2=15^2+b^2-2*15*b*cos(90)
cos(90)=0->
(b+3)^2=15^2+b^2
b^2+2*3*b+3^2=225+b^2
6b+9=225
6b=216
b=36=CE

DE=CE+3=36+3=39

OlgaM077 [116]

Answer

Find out the  how many traffic lights are there on elm street .

To prove

As given

Elm street is 3.6 kilometers Long .

There are sets of 4 traffic lights every 0.6 kilómeter.

i.e

Traffic\ lights\ in\ one\ kilometer = \frac{4}{0.6}

Now

Traffic light in 3.6 kilometers = Traffic light in one kilometer × 3.6

Traffic\ light\ in\ 3.6\ kilometers = \frac{4\times 3.6}{0.6}

Traffic light in 3.6 kilometers = 24

Therefore Traffic light in 3.6 kilometers are 24 .
