5. Which of the following are true statements? Select all that apply. (2 points)
sin 50° = sin 22° cos 28° + cos 22° sin 28°
sin 50° = sin 72° cos 22° - sin 72° cos 220
cos 50º = cos 64º sin 14° + cos 64 sin 14°
tan50° = tan 52°+tan 2°/ 1-tan 52°tan 20
tan50°=tan 11° + tan 39°/ 1-tan 11°tan39°

1, 3, 5

Step-by-step explanation:

Solving them each

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
