Finding the missing “leg” of the triangle

24

Step-by-step explanation:

I'm not sure if this is correct. I just want to help you and have brainiest

so I used this formula

c²=a²+b²

26²=a²+10²

676=a²+100

676-100=a²

576=a²

√576=24

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
