Find the value of the variable What is x?
yaroslaw [1]

Answer:

x = 7

Step-by-step explanation:

I think there may be other ways to do this ... but this is one I  guess....

one angle= 90 ( given)

the other = 45 (given)

the third = 90 + 45 + a = 180  

(all angles of triangles is 180 [angle sum property])

                a = 180 - 135

                   = 45

The base angles are equal so that means it is a isoscles triangle. In isoscles triangle, two sides are equal ,  so

if one side is 7

the x is 7 too

(as it cant be the hypothenus)

I think this is right

What multiplies to negative 24 and adds to 2
exis [7]
Let us assume the two numbers to be "x" and "y".
Then
xy = - 24
x = - (24/y)
And
x + y = 2
Putting the value of x from the first equation in the second equation, we get
x + y = 2
- (24/y) + y = 2
- 24 + y^2 = 2y
y^2 - 2y - 24 = 0
y^2 - 6y + 4y - 24 = 0
y(y - 6) + 4(y - 6) = 0
(y - 6) (y + 4) = 0
When
y - 6 = 0
y = 6
Then
x + y = 2
x + 6 = 2
x = 2 - 6
   = -4
And when
y + 4 = 0
y = -4
Then
x + y = 2
x - 4 = 2
x = 2 + 4
   = 6
So the two unknown numbers are -4 and 6.
