Answer:
6
Step-by-step explanation:
tan 45 = 6 / x
1 = 6 / x
x = 6
Note :
Tan 45 value = 1
To expand just go (3x+y)(3x+y)(3x+y)(3x+y) then use something my teacher calls the "crab claw" for just the first 2 brackets by doing 3x*3x + 3x*y + y*3x + y*y to get (9x^2+3xy+3xy+y^2) then find the like terms to get (9x^2+6xy+y^2) which would be the same for the other 2 brackets to get
(9x^2+6xy+y^2) (9x^2+6xy+y^2) then expand them by going 9x^2*9x^2... now you should try the rest. Hope this is the answer you wanted
Answer:
7
Step-by-step explanation:
Pythagorean theorem. 24^2+b^2=25^2
Simplify
576+b^2=625
b^2=49
b=7
