Were there angles given? you just didn't quite give enough information to do this quickly. But I'll try, so a^2 plus b^2 is 400, and a+b is over 20, so we know that much. Therefore we find two numbers that equal 400 when squared and added and are more than 20. And since it's isosceles the other two sides must equal, the number you end up getting is 14.14213561 for the two sides. Then to find area you are gonna square that since it's base times height and get 200 then divide that by two, which is 100 units^2.
Answer: I believe it is 20
Step-by-step explanation: it is in intervals of 2 the blue mark Iis is at 20
Answer:
8.06
Step-by-step explanation:
Use Pythagorean theorem to determine the hypotenuse
5 is the median of those number
I think it would take an average of both the numbers so first find the average of 60 and 90 by adding and dividing by two. You will get 75 seconds. That is the answer
