Given that the isosceles triangle has sides √45, √45 and x.
The triangle has a height of 3 units.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the formula,

Where b is the base of the triangle, a is the sides of the isosceles triangle and h is the height of the triangle.
Substituting
,
and
in the above formula, we get;

Squaring the terms, we have;

Subtracting, we get;



Thus, the value of x is 12
Hence, Option B is the correct answer.
STEP 1:
identify variables and equations
x= larger number
y= smaller number
FIRST EQUATION
x + y= 42
SECOND EQUATION
y= 2x - 63
STEP 2:
substitute the y value in second equation in for y in first equation
x + y= 42
substitute y value from 2nd equation
x + (2x - 63)= 42
combine like terms
3x - 63= 42
add 63 to both sides
3x= 105
divide both sides by 3
x= 35 larger number
STEP 3:
find y value; substitute step 2 x value into either original equation
x + y= 42
35 + y= 42
subtract 35 from both sides
y= 7 smaller number
ANSWER: larger number is x= 35; smaller number is y= 7.
Hope this helps! :)

Answer:
Laura wants to buy a coffee mug in a shop. She has x dollars, which isn't enough to pay for the coffee mug. As a solution, she asks her friend to help pay for the coffee mug. Her friend contributes 11 dollars in addition to Laura's x dollars, and luckily, her 11 dollars either add up to 23 or exceed it.
