1 and 3, same explanation as last time
Step-by-step explanation:
angle MRP
angle PRS=angle RPN (alternate angles)
2x+x+x+78°=180°(sum of angles of a triangle)
4x+78°=180°
4x=180°-78°
4x=102°
4x/4=102°/4
x=25.5
Answer:
x=4 and y=3
Step-by-step explanation:
put one of the equations in slope form and solve
It took 4 stops, im guessing you probably shouldnt take my advice though
So firstly, add both sides by 6: ![\frac{1}{4}w=2](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7Dw%3D2%20)
Next, multiply both sides by 4, and your answer will be ![w=8](https://tex.z-dn.net/?f=%20w%3D8%20)
