Answer: 8² = 4² + 5² - 2(4)(5) cos(P) which is the third optionExplanation: The general rule of cosine is: a² = b² + c² - 2bc*cos(A) In our triangle: a is substituted by p = 8 cm b is substituted by n = 4 cm c is substituted by m = 5 cm A is substituted by P which we want to find Replace the variables in the general equation with the givens as follows: p² = n² + m² - 2mn*cos(P) 8² = 4² + 5² - 2(4)(5) cos(P) Hope this helps :)

You want to solve for x so add 18 from both sides of the equal sign. making it 3x=12. then divide both sides by 3 making x=4. x is 4.
Answer:
3 vertices
Step-by-step explanation:
Vertices are the "points" of a 2D figure. In this case, we see the 2D figure as a triangle. There are 3 points on the triangle, so there are 3 vertices .

Answer:
this is simplify 1/16 x4 y4
(9x+5) - (6x-8) = 9x+5 - 6x+8 = (9x-6x) + (5+8) = 3x+13 ___ (4x+10) - (-3x+5) = 4x+10 + 3x-5 = (4x+3x) + (10-5) = 7x+5
