Suppose a triangle has sides a, b, and c, and that a2 + b2 < c2. Let be the measure of the angle opposite the side of length
c. Which of the following must be true? Check all that apply. A. the triangle is not a right triangle.
B. a^2+b^2-c^2=2abcos(theta)
C. cos(theta) > 0
D. cos(theta) < 0
Answer:So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.
