Answer:
The first equation answer would be 70, whilst the second equation's answer is 160. I think this would be the correct answer:
20(2) + 30(1) = 70.
20 (8) + 30(0) = 160.
Step-by-step explanation:
Basically, you would do 20(2) + 30(1) for one of the equations and 20(8) + 30(0) for the other equation. Those equations would give you the answer.
Answer:
140
Step-by-step explanation:
Consider a square for just a second. It has 4 angles each of 90 degrees. The total number of degrees in a square is 4 * 90 = 360.
It should be at least an appeal to your intuition to say that a quadrilateral has a total of 360 degrees.
Therefore the ratio you have been given must have 4 angles that add to 360.
2x + 3x + 6x + 7x = 360
18x =360
x = 20
So the 4 angles are
2* 20 = 40
3*20 = 60
6*20 = 120
7*20 = 140
Total 360
The largest angle is 140
Pythagoras theorem, answer is sqrt69 or 8.307 to 3dp.
I have no answer, because you have no question.
