Answer:






Step-by-step explanation:
step 1
Find the value of x
we know that
----> by alternate interior angles
solve for x
Group terms


step 2
Find the measure of angle a
we know that
----> by vertical angles
substitute the value of x

step 3
Find the measure of angle b
we know that
----> by supplementary angles (form a linear pair)
we have

substitute


step 4
Find the measure of angle c
we know that
----> by vertical angles
we have

therefore

step 5
Find the measure of angle d
we know that
----> by corresponding angles
we have

therefore

step 6
Find the measure of angle e
we know that
----> by alternate exterior angles
we have

therefore

step 7
Find the measure of angle f
we know that
----> by vertical angles
we have

therefore

Doubling in size,
if the whole dish is filled in an hour (all of it)
how long does it take to fill 1/2 dish?
notice that
1/2 doubled=1/2 times 2=2/2=1 whole dish
therefor it only doubled one more time from the 1/2 point
1hour=all
1hour-6mins=1/2 dish
1hour-6mins=60-6=54 minutes
answer is 54 minutes
Answer:
C = 2
Step-by-step explanation:

Answer:
Segunda etapa= 123.75 metros
Step-by-step explanation:
Altura total= 225 metros
<u>En la primera estapa subió el 20% (un quinto):</u>
Primera etapa= 225*0.2= 45 metros
<u>En la tercera etapa subió 25% (un cuarto):</u>
Tercera etapa= 225*0.250 56.25 metros
Ahora debemos determinar cuánto subió en la segunda etapa:
Segunda etapa= altura total - total subido
Segunda etapa= 225 - (45 + 56.25)
Segunda etapa= 123.75 metros
Answer:
A,C
Step-by-step explanation:
sin 2x=sin (x+x)=sinx cos x+cos x sin x=2 sin x cos x
or =2 cos x sin x
[sinx cox=cos x sin x ]
