If the angle in B is 45º, that means the angle in A is also going to be 45º, considering it's a right triangle, so AC and BC are they have the same length.
Then using Pythagoras, you'll get that AC^{2} + BC^{2} equals AB^{2} .
Now, you know that AC=BC and that AB=24.
So you'll get 2AC^{2} =24^2 . You do the square root in both sides and you get that 2AC=24 and AC=12.

Now that you know that both AC and BC equal 12, you can find the area by just multiplying them and then diving them by 2. (The formula for the area of a triangle is half base multiplied by height, and in a right triangle, if a cathetus is the base, the other cathetus<span> will be the height)

And so the area is equal to 72.</span>

Factor completely <br> 4x^2 + 24x - 64
lara31 [8.8K]
First see you can factor out 4. What is left is x^2 + 6x - 16.
That can be factored as (x+8)(x-2) so the total factorization is

4(x+8)(x-2)

What is the volume of the square pyramid with base edges 4 m and height 3 m
olya-2409 [2.1K]

16 m³

Step-by-step explanation:

Step 1:

Here we are going to find the volume of square pyramid.

Volume of square pyramid = (1/3) × (Base)^{2} × (Height)

Here base = 4 m

         Height = 3 m

Step 2:

Volume = (1/3) × (4 × 4) × 3

              = 16 m³

Find the distance between the points (0,2)and (-5,-9)The answer must be a whole number or a fully simplified radical expression
LiRa [457]

Answer:

d = \sqrt{146}

Step-by-step explanation:

d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d= \sqrt{(-5-0)^2+(-9-2)^2}\\d= \sqrt{(-5)^2+(-11)^2}\\d= \sqrt{25+121}\\d= \sqrt{146}
