Perimeter is 40 and area is 60 something. Sorry if I’m wrong I tried to help you tho. But If I am wrong look at other people’s answers
21 and 22 because 21+22=43
I have attached a diagram of the triangle described.
We can use any of the trigonometric functions to find angle x. Remember, SOH CAH TOA. And since we're finding the angle, we'll need to use an inverse trigonometric function. For this problem, I'll be using the sine function.
sin(x) = 84 / 85
x = sin^-1(84/85)
x = 81.2026 degrees (feel free to round to however many places you need)
Hope this helps!! :)
