Step-by-step explanation:
please beggggggg
The Pythagorean Theorem is used to find the unknown length of a side of a triangle or (in your case) a pyramid. The Pythagorean theorem is a^2 + b^2 = c^2 with c being the hypotenuse (longest side). Use this theorem to find each of the lengths of the sides of the pyramids that you need to find the volume of each respective pyramid.
Hope this helps!
The formula you need to know is that the side opposite of the 30° angle is always half the hypotheneus. For example in question 2 X should be 6 since 3 is opposite side of the angle 30°. In a 45 45 90 triangle, it is important to know that the straight sides are always the same length (since they are the same angle). For example in question 9, v is also 9√2.
When you have two sides, you can figure out the third side with a² + b² = c² since they are all right triangles. Good luck
