Answer: an triangle's angles will always add up to 180 so: 54+82=136 180-136=56 x=56

We also know that vertical angles are the same. (angles across from each other) and that the sum of these 4 angles will be 360. using this, we get 56+56=112 and then we do 360-112=248 248/2=124 So y=124.

I hope this helps.

y = 180° - x

x = 180° - (82° + 54°) } => y = 82° + 54° = 136°

What is the equation of the following line written in general form (4,5) (1,2)

a_sh-v [17]

The answer is y= 1 + 1x

because the slope is 1 shown by this table:
1,2
2,3
3,4
4,5

and if the slope is one then 2-1 is 1 and the y intercept is 0,1.

if A and B together can do a piece of work in 10 days and B along can do it in 15 days, how many part of the work does A complet

anzhelika [568]

Answer:

1/5

Step-by-step explanation:

Well work can be defined as: $work = rate \ *\ time$

where rate=amount of work that can be done in one unit of time

let a = rate of work A does in a day

let b = rate of work B does in a day

this means that: $10a + 10b=1$ where work=1 and it just means the entire job has been completed.

Since b can do it alone in 15 days, this means that: $15b=1$

If we divide by 15 here, we get the equation: $b=\frac{1}{15}$

We can now use this definition to substitute it into the first equation we made.

$10a + 10(\frac{1}{15}) = 1$

Multiply the 10 and 1/15

$10a+\frac{2}{3}=1$

subtract 2/3 from both sides

$10a=\frac{1}{3}$

Now divide both sides by 10

$a=\frac{1}{30}$

Now multiply this by 6, since we a represents the amount of work that can be done in a day, we want to find how many parts of the work can be done by a in 6 days

$6a=\frac{6}{30}$

Now divide both the numerator and denominator by 6

$a=\frac{1}{5}$
