The distance between 2 points P(a, b) and Q(c,d) is given by the formula:
,
Apply the formula for the points M(6, 16) and Z(-1, 14):
which rounded to the nearest tenth is 7.3 (units)
Answer: 7.3 units
Can you show the expression plz
Unlike the previous problem, this one requires application of the Law of Cosines. You want to find angle Q when you know the lengths of all 3 sides of the triangle.
Law of Cosines: a^2 = b^2 + c^2 - 2bc cos A
Applying that here:
40^2 = 32^2 + 64^2 - 2(32)(64)cos Q
Do the math. Solve for cos Q, and then find Q in degrees and Q in radians.
