Find the value of x and y

Mathematics

According to google, the red marks mean those two lines are the same length.  If that's the case, we know that x is the angle in both corners of the lower triangle.  We also know that because the angle of a straight line is 180, that the top angle of the bottom triangle is 140, because it's divided into two parts, one of which is 40.  That leaves 140 for the rest.  Now we know that there are 180 degrees in a triangle so x=(180-140)/2 = x=20degrees.
The right angle in the left corner is 90 degrees.  It is divided in two parts, the lower one of which we just found to be 20.  So the other part must by 70deg.
So for the upper angle y, we have 180-70-40= y=70degrees

-8= 3-5(x+6) solving algebraicaily​
SOVA2 [1]

Let's solve your equation step by step

-8=3-5(x+6)

Step 1: simplify both sides of the equation

-8=3-5(x+6)

-8=3+(-5)(x)+(-5(6) (distribute)

-8=3+-5x+-30

-8=(-5x)+(3+-30) (combine like terms)

-8=-5x+-27

-8=-5x-27

Step 2: flip the equation

-5x-27=-8

Step 3: add 27 to both sides

-5x-27+27=-8+27

-5x=19

Step 4: Divide both sides by -5

-5x/-5 = 19/-5

Answer : x= -19/5

Answer:

down below

Step-by-step explanation:

straight lines are 180 degrees and you have 2 angles on a line. one of which is 72 and the other is unknown. It is solved for below.

180=72+x\\180-72=72+x-72\\108=x

your missing degree is 108.

i may not be right, if i'm not i am very sorry.

Matt bought a home in 2001 and paid $150,000 for it. He sold the home for $450,000. How much of the profit on his home will be t
butalik [34]

Answer:

profit to be taxable will be  $300,000

Step-by-step explanation:

Matt home cost = $150,000

Matt sold his home for = $450,000

so,

cost price will  be  $150,000

selling price will be $450,000

         profit = selling price - cost price

         profit  =  $450,000  -  $150,000

         profit  =  $300,000

hence the taxable amount for his home this year will be $300,000
