The complete question is shown in the figure below. As you can see one square units is well shown in the graph. So we can conclude that the distance between two consecutive points is 1 unit. If so, then we can calculate the area of the parallelogram as follows:

Then, finding CB by Pythagorean Theorem:

And:

Therefore:

Answer:
Step-by-step explanation:
46+x=77 subtract 46 from both sides
x=31
1. 2/7
2. 2/15
3. 5/24
4. 2/11
5, 10 ,15
divide each by 5
1,2, 3
so the ratios should be 1,2,3
Metal 1 : divide by 150
1,2,4
Metal 2 divide by 130
1,2,3
Metal 3 divide by 310
1,2,3
Metal 4 divide by 140
1,2,3
Metal 1 is not proportional
