Question 641702: Starting at the center, designated as C, construct an isosceles right triangle with a congruent leg pointing north from the center, and the other congruent leg pointing east from the top of the first leg. The hypotenuse is at a 45-degree angle pointing northeast from C. Make each congruent leg 2 centimeters in length. Using the hypotenuse of the first triangle as one leg, and another 2-centimeter leg at right angles to it on the outside, construct a second right triangle. Again, the hypotenuse of this new triangle will be a segment coming from C and will point (approximately) east-by-northeast. Repeat, each time using the previous hypotenuse as the longer of the two legs of the new right triangle, and adding a leg of 2 centimeters to the outside end, then forming the new hypotenuse from C. Continue this process until your combined figure has wrapped all the way around the center, so the next triangle you construct overlaps the first one.
Questions
A. What is a common name for this figure?
B. How many triangles were constructed before the algorithm terminated?
C. What is the figure’s total area?

Question 647498: The question I am doing now says "Find the measure of the unknown side" and it shows a picture of a triangle, it says side a is 13mm, side c is 5mm and you're trying to find side b. I know how to do pythagorean therom when you need to find side c, but how do you do it when you need to find side b?

Question 652002: Please can you help me solve this. I tried but i have no idea if it is right.
A cuboid box has dimensions 40cm x 30cm x 20cm. The box is to hold knitting needles. What is the size of the biggest knitting needle the box can hold ?
I tried a few things such as:
n = 44.7cm to 1 d.p.
Am I doing it right or not ?

Question 662797: I think Pythagorean theorem will help here:
Two Perpendicular diameters are drawn in a circle into four equal quadrants. A circle is drawn in one of the quadrants so that it touches both diameters and also the 1m radius circle. What is the radius of the new circle?
Could you explain how to work it out as well? I am only 12 and was given this problem for an extension class.

Question 666808: This is the problem I have to solve I have no idea where to start? Please help
Ahmed has half of a treasure map,which indicates that the treasure is buried in the desert 2x + 6 paces from Castle Rock. Vanessa has the other half of the map. Her half indicates that to find the treasure, one must get to Castle Rock, walk x paces to the north, and then walk 2x + 4 paces to the east. If they share their information, then they can find x and save a lot of digging. What is x?
