Answer:

25°, 65°

Step-by-step explanation:

Essentially, you want two angles that have a sum of 90 degrees and a difference of 40 degrees.

The smaller is half the sum less half the difference: 90/2 -40/2 = 45 -20 = 25.

The larger is half the sum plus half the difference: 90/2 +40/2 = 45 +20 = 65.

Of course, once you know either value, you can add or subtract the difference (as needed) to find the other value.

The two angles are 25° and 65°.

<em>Additional comment</em>

There are many ways you can arrive at this conclusion. Algebraically, we can write ...

a+b = sum

a-b = difference

Adding these two equations gives ...

2a = sum +difference

Multiplying by 1/2, we get ...

a = 1/2sum +1/2difference . . . . . . as described above

Subtracting the difference gives ...

b = a -difference = 1/2sum -1/2difference

Factor completely x^2-48

fredd [130]

Answer: $(x-7)(x+7)$

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below;

- Make the equation equal to zero:

$x^{2}-49=0$

-Add 49 at both sides:

$x^{2}=49$

- Now, you must take the square root of both sides of the equation, then you obtain the following roots:

$x=\sqrt{49}\\x_1=7\\x_2=-7$

- Then you have:

$x^{2}-49=$ $(x-7)(x+7)$
