his and Vanessa’s paces should end up in the same place. I did this out on scratch piece of paper and I saw that it forms a right triangle with 2x + 6 being the length of the hypotenuse, and x and 2x + 4 being the legs of the triangle. Now I know how I can use the Pythagorean Theorem to solve for x. The Pythagorean Theorem states that in every right triangle with legs of length a and b and hypotenuse c, these lengths have the formula of a2 + b2 = c2. Let a = x, and b = 2x + 4, so that

Castle Rock and Vanessa half says that when she gets to Castle Rock to walk x paces to the north, and then walk 2x+4 paces to the east. So with all the information I have I need to find x. the Pythagorean Theorem states that in every right triangle with legs of length a and b and hypotenuse c, which have of a relationship of a2+b2=c2. In this problem I will let a=x, and b= 2x+4, and c=2x+6. So know it time to put the measurements into the Theorem equation; 1) X2+ (2x+4)2=(2x+6)2 this

1. N/a 2. using Law of Sines and Law of Cosines. You get two different triangles. The one combination you can't have is where A is opposite the b. Maybe your notation already specifies this, but I don't think so, otherwise there is no problem. If you try to construct a triangle with the 70 degree angle opposite the side of length 5, the Law of Sines would give sin x = (7/5)sin 70 = 1.316, which is impossible. With angle A = 70 opposite the side of length 7, the Law of Sines gives sin x = (5/7)sin
