x=96

all interior angles equal 180

Subtract exterior andgles by 180 to get interior angles because they are supplementary

180-134=46

180-130=50

Get the third angle inside the triangle

180-50-46=84

subtract by 180 to get x because they are supplementary

180-84=96

Therefore x =96

Use the relationship between the sine and cosine functions to fill in each blank .

rjkz [21]

Answer:

sin(12°)

Step-by-step explanation:

Because sine and cosine are cofunctions, we can use the relation sin(90° - θ) = cosθ to show that cos(78°) = sin(90° - 78°) = sin(12°)

Two parallel lines are crossed by a transversal.

nadya68 [22]

Answer:

Option B) y = 50

Step-by-step explanation:

We are given the following information:

Two parallel lines are crossed by a transversal.

The attached image shows the intersection of transversal and the angles.

As clear from the image, the given pair of angles form alternate interior angles.

If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent or equal

Thus, y = 50 degree
