a is 45 degrees and b is 45 degrees
Answer:
10.) Proportional
11.) Not Proportional
Step-by-step explanation:
The graph in number 10 is steady so it is proportional and crosses the origin. Number 11 is not proportional because it does not cross the origin.
The ratio is 11 : 7. I.e the number of red apples are 11 and that of green are 7
Answer:
x=6
Step-by-step explanation:
If b in in the middle of A and C then you would set AB equal to BC and solve
Answer:
x = 6.5
Step-by-step explanation:
Since all angles in a triangle adds up to 180°, we have:
10x - 10 + 10x + 8 + 8x = 180
28x - 2 = 180
28x = 182
x = 182/28 or 6.5
