Answer:
5√202
Step-by-step explanation:
By Pythagoras theorem,
x^2 = 45^2 + 55^2
= 2025 + 3025
x^2 = 5050
x = 5√202

Answer:
½ ln 3
Step-by-step explanation:
∫ sec²x / tan x dx
If u = tan x, then du = sec²x dx.
∫ du / u
ln|u| + C
ln|tan x| + C
Evaluate between π/4 and π/3.
ln|tan(π/3)| + C − (ln|tan(π/4)| + C)
ln|√3| + C − ln|1| − C
ln(√3)
½ ln 3
