Well I certainly understand why you are having grief. I wonder what we know about this thing? The bottom triangle is easy enough to figure out, but are the lines leading up to it parallel? If they are then 5.2 is not correct, or the right
angle symbol is meant to connect to the vertical line closest to us.
What's all the writing to the left and right. What does it say?

Finally what do you know? Can you find area using Heron's Formula for area. I'm going to hold off saying much. You can put a remark somewhere. The magic editor will pick it up and tell me you've done it.

Jose has $2.50 in nickels and dimes in his jar. If he has 11 more nickels than dimes, how many dimes does he have?

Jose has $2.50 cents in total,
We need an equation to solve this. We will let d=dime.
dime=.10
nickel=.05

.10d + .05 (d + 11)=2.50

.10d + .05d + 0.55= 2.50

.15d + 0.55 = 2.50

.15d= 1.95

d= 13

There is 13 dimes. To get the nickels, you just add the 11 to 13 and you get 24 nickels.
