Answer:
27
Step-by-step explanation:
Note that since VX and XZ are both line segments, <VWX and <XYZ both equal 180 (also known as a straight angle). Also, note that the sum of the angles in a triangle are 180 degrees. Now, let’s start.
Finding angles of the triangle:
<WYX = <XYZ - <WYZ = 180 - 4x
<XWY = <XWV - <VWY = 180 - 6x
Using the sum of angles in a triangle and substituting these values in:
180 = <X + <WYX + <XWY = 90 + (180 - 4x) + (180-6x) = 450 - 10x
270 = 10x
<em>27 = x</em>
We are done! I hope this helps! :)
Answer:
5
Step-by-step explanation:
its where the line matches up.
-7r+13=-71
move 13 to the other side
sign changes from +13 to -13
-7r+13-13= -71-13
-7r= -84
divide both sides by -7 to get r by itself
-7r/-7= -84/-7
Answer: r= 12
