Hello from MrBillDoesMath!
Answer:
csc (90° – x) = sec (x )
sin (90° – x) = cos (x )
tan (90° – x) = cot (x)
cos (90° – x) = sin (x )
cot (90° – x) = tan (x )
sec (90° – x) = csc (x)
Thank you,
MrB

Step-by-step explanation:
Using Pythagorean Theorem, 3² + 4² = 5²
U= 28
Step by step solution
add 23 to both sides
U-23+23=5+23
hence
U=28
