Find the values of x and y, given the diagram below. image shows two intersecting lines. the measures of three of the angles are shown. one of the two vertical angles has measure 2x + 1 degrees and the other has measure 45 degrees. the third angle shown has measure 5y. A. x = 22, y = 9 B. x = 22, y = 27 C. x = 23, y = 9 D. x = 23, y = 27
What do you know about the measures of vertical angles?
vertical angles are reflexive/equal
Right. Their measures are equal. Set the measures of the 2 vertical angles equal to each other, and solve the equation for x.
That's how you find x.
Have you gotten x?
im struggling but im trying
Did you understand what I suggested you do above?
The two vertical angles measure 2x + 1 and 45. Right?
yeah
You know that vertical angles have the same measure. You said so above. That means that 2x + 1 must equal 45. Now that can be written as an equation: 2x + 1 = 45
Now we need to solve this equation to find x.
You want to isolate x. The first step is to subtract 1 from both sides.
x=22
