Answer is C (108).

All 4 angles combined are always 360 degrees. In this case if you add 2 angles combined thehy are always 180 degrees.

If we know angle 1 is 72 than angle 3 is 180-72
And 180-72 =108

Since Angle 1 and 3 are vertical angles, they are congruent.

In this case, because Angle 1 is 72°, Angle 3 is 72°, or D.

Answer: True for all <em>b</em>.

Step-by-step explanation: To tangent a equation, find if the variable is true.

1. Add 56 to both sides.

63b - 56 + 56 = 63b - 56 + 56 = 7

2. Simplify.

63b = 63b

3. Simplify again for your answer.

0 = 0

Hence, both sides are equal.

Let me know if you have any questions.

In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angl

Musya8 [376]

Answer:

angle Y = 90 degrees

Step-by-step explanation:

Since it is stated that angle x forms a straight line with the 50 and 50 degree angles, and that angle x is vertical to angle y, we can do 40+50+y=180 to find angle Y.
