Answer:
∠4
Step-by-step explanation:
An angle of depression is measured from the horizontal downwards.
This is ∠4 in the diagram
Keeping in mind that 16 = 2*2*2*2, thus 16 = 2⁴
The sign of the product would be the postitive sign because all three integers have the same sign.
Factor because if we have
yz=0 then we can assume y and/or z=0
so factor
so the easiest way is to find what 2 numbers add to -6 and multiply to get 9 so
we know that they must be both - because we must have x+x=(-) and x^2=+ so therefor they must be negative
factors of 9=3 and 3 so
-3 and -3
-3+-3=-6 perfect
(z-3)(z-3)=0
set each to zero
z-3=0
add 3
z=3
z=3 is the answer
