Step-by-step explanation:
(3)
Given cosΘ = -
Then by Pythagoras' theorem the third side is 3 ( 3,4, 5 triangle )
Since Θ in second quadrant then sinΘ > 0
sinΘ =
Using the trigonometric identity
sin2Θ = 2sinΘcosΘ, then
sin2Θ = 2 × × - = -
(4)
Using the trigonometric identity
cos(x - y) = cosxcosy + sinxsiny
note cos15° = cos(45 - 30)°
cos(45 - 30) = cos45cos30 + sin45sin30
= ( × ) + ( × )
=
Answer:
straight line and line goes through the origin.
Step-by-step explanation:
without a graph, you will need to divide y/x to seeing there is a constant rate or a constant number every time you divide.
Area of a triangle: (1/2)bh, where b = base and h = height
(1/2) x 4 x (11/2)
= (4/2) x (11/2)
= 2 x (11/2)
= 11
