That would be 1.175 Answer
That is called an acute angle if it’s more than 90 degrees it’s called o tuse angle
I hope this helps you
let's find AB
AB=square root of 2^2+3^2
AB=square root of 13
cosO=2/sqrt13
sinO=3/sqrt13
tgO=3/2
ctgO=2/3
I believe the answer would be: 4+y<15
Sum means we are adding. 1 + y has to be greater than or equal to 5, therefore,
