On graph paper, simple plot these two points. Then draw a line that hits both of these points. Then you will find that the line you drew never entered the first quadrant (the one on the top right side)
If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.
b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°
Answer:
1:3
Step-by-step explanation:
4:12 simplified is 1:3. for every 1 dark blue there are 3 light blues.
They are not equivalent because when you are doing ratios they are not interchangeable
Answer:
Step-by-step explanation:
2x-3y=12
y=2/3x-4
