Answer:
12ft
Step-by-step explanation:
use sin cos tan method
here, we can see 6ft as adj to the angle and the ladder as hypotenuse
so, adj/hyp = cosθ
--> 6/hyp = cos60
--> hyp = 6/cos60
--> hyp, length of ladder = 12ft
Answer:
-1 and 10
Step-by-step explanation:
x2-9x-10
=x2-10x+x-10=0
=x(x-10)+1(x-10)
=(x+1)(x-10)
