How do you solve for x and y?

Mathematics

Amiraneli [1.4K]3 years ago

Answer:

x = 60°, y = 30°

Step-by-step explanation:

The sum of the triangle angles is always 180°

Therefore 90° + x + y = 180°

It is also known that x = 2y

// combine the given value of x into the previous expression

90° + 2y + y = 180°

2y + y = 180° - 90°

3y = 90°

// divide both sides by 3

y = 30°

// then combine the given value of y into the expression x = 2y

x = 2 * 30°

x = 60°

natima [27]

Answer:

Amount received by Aman's Wife   = $4000

The expression which shows the amount received by his son = x+ 10000

Step-by-step explanation:

The total amount Aman has = $9000

Let us assume the amount his daughter receives = $x

So, the amount his wife received = 2 x (Amount received by Daughter)

= 2 x ($x)  = 2 x

And the amount his son received =$1000 +  (Amount received by Daughter)

= 1000 x ($x)  = x+ 10000

According to the question:

Amount of ( Daughter's  + Wife's  + Son's)  share  =  $9000

x + 2x + x + 10000 = $9,000

⇒4 x  = 9000 - 1000

or, 4 x = 8000

⇒ x = 8000 / 4 = 2,000

⇒ x = $2,000

So, the amount received by Aman's Wife  =  2 x + 2 ($2000) = $4000

The expression which shows the amount received by his son = x+ 10000
