Pretty sure it’s acute because 18 squared is less than the sum of 10 squared and 16 squared
No because if you could use distributive property you would do 5*7 then 5*10 then you would get 35*50 which equals 1,750 and if you do it like it’s set up you would do 7*10 first cause PEMDAS so parentheses first so 7*10 is 70 then 70*5 is 350 and that’s not even close to the other answer so no you can’t .
I believe your answer is D. 77.
Answer:
Takin LHS
cot²a . cos²a
cos²a/sin²a-cos²a
cos²a -cos²a.sin²a/sin²a
cos²a(1-sin²a)/sin²a
cot²a.cos²a LSH=RHS PROved
