Answer:

That is truth

Step-by-step explanation:

Remember that sin(x-y)= sin(x)*cos(y) + sin(y)*cos(x)

Lets evaluate x=360, y=theta

sin(360-theta)=sin(360)*cos(theta) -sin(theta)*cos(360)

Also, remember that sin(360)=sin(0)=0

Cos(360)=cos(0)=1

Thus

Sin(360-theta)=-sin(theta)

11. Consider the figures below. Find the value of y to prove that the two triangles are congruent by ASA.

Answer:

y = 8

Step-by-step explanation:

You will get the same value for y whether you approach the problem by making corresponding angles equal, or by making corresponding sides equal. The equation for the sides takes less work to solve.

2y -3 = y +5

y = 8 . . . . . . . . add 3-y to both sides

_____

<em>Check</em>

This value of y makes the angles ...

(6y -5)° = (6·8 -5)° = 43°

(4y +11)° = (4·8 +11)° = 43°

Corresponding angles and the side between them have the same measures, so the triangles are congruent by ASA.
