Question
Angle STV is a right angle.The measure of angle STW is 55°.The measure of angle WTV is x°.What is the value of x?
Solution
Since STV is a right angle, it measures 90 degrees.
We know that the sum of the angles in a triangle is 180 degrees.
So, we can set up the equation: 90 (for STV) + 55 (for STW) + x (for WTV) = 180.
Adding 90 and 55 gives us 145.
So, the equation is now 145 + x = 180.
Subtracting 145 from both sides of the equation gives us x = 180 - 145.
Therefore, x = 35 degrees.
