Answer:
120 degrees
Step-by-step explanation:
Attached is a screenshot.
y = 180 - 50 - 70 = 60.
x + y = 180, so x = 120
Remember to try to use parallel lines when you can
The second uses the same method, just the opposite side.
This question is worded slightly strangely but I believe I understand it.
To eliminate x, multiply the second equation by 8, so that it becomes 4x + .8y= 96
Then you can subtract 4x on the top by 4x on the bottom to eliminate it.
Y=3x-2 is the equation :^}
Answer:
55 degrees (a)
Step-by-step explanation:
complementary means they equal 90 degrees
so 90-35= 55 degrees
Answer: 1 1/3
