Question

Angle STV is a straight angle the measure of angle STW is 125 the measure of angle WTV is X what is the value of X

Answer 1

Answer:

x = 55°

Step-by-step explanation:

If ∡STV is a straight angle (or 180°) and ∡STW is 125°, then we can assume that the angles look something like this

     V |            / W

        |          /

        |  x°  /

     T |   /

        |  125°

        |

     S |

Now this means that to get ∡WTV, we need to subtract ∡STW from ∡STV, which would look like this:

180 - 125 = 55

This means ∡WTV (or x) = 55°
