What do you need to solve for?
X=r-4/7-s
S=-r/x+4/x+7
R=-sx+7x+4
Answer:
Since the legs of the right triangle measure x + 1 and x + 15, respectively, and since the hypotenuse measures x + 17, the Pythagorean Theorem can be used as follows: (x + 1)2 + (x + 15)2 = (x + 17)2. This equation becomes (x2 + 2x + 1) + (x2 + 30x + 225) = x2 + 34x + 289, which then becomes 2x2 + 32x + 226 = x2 + 34x + 289. When all the terms are moved to one side, the equation becomes x2 – 2x – 63 = 0, and when the left side of the equation is factored, it becomes (x – 9)(x + 7) = 0. At this point, it seems as if x can equal 9 or –7, but if x were –7, one of the legs would have a negative length, and this is impossible. For this reason x equals 9, and the legs of the triangle measure 10 and 24, respectively, while the hypotenuse measures 26. Since cosine is
length of adjacent leg
length of hypotenuse
, the cosine of angle C is
24
26
, or

Answer:
1002
Step-by-step explanation:
Plug in the values for a and b that you are given.
50(20) - 2(2) + 6 = ?
1000 - 4 + 6 = 1002
Answer: g = 5.9
Step-by-step explanation:
SINE RULE
5 / sin(39) = g / sin(48)
so g = 5 / sin(39) * sin(48)
so g = 5.9 to the nearest tenth.
