This is a right angle triangle 
So we can use the tangent 
tan x = 5/20 
tan x= 0.25 
x=tan^-1 (0.25) 
x= 14.04 degrees 
So yes you're correct

Answer:

\large\boxed{|x+7|\geq2}

Step-by-step explanation:

Look at the picture.

|x-a|\geq b\\\\a=\dfrac{-9+(-5)}{2}=\dfrac{-14}{2}=-7\\\\b=-9-(-7)=-9+7=-2\\b=-5-(-7)=-5+7=2\\\\|x-(-7)|\geq2\\\\|x+7|\geq2\\\\Check:\\\\|x+7|\geq2\iff x+7\geq2\ \vee\ x+7\leq-2\qquad\text{subtract 7 from both sides}\\\\x+7-7\geq2-7\ \vee\ x+7-7\leq-2-7\\\\x\geq-5\ \vee\ x\leq-9\qquad CORRECT\ :)

Help me pls and pls explain
andrey2020 [161]

Answer:

Step-by-step explanation:

I am not clear your question.

5^(-2) / ( 5^(-3) * 5^(4))

When base is equal at multifaction index should be add.

ie. (-3)  + 4 =1

5^(-2) / ( 5^((-3) +4))

5^(-2) / ( 5^(1))

When base is equal at division index should be substract.

5^(-2) / ( 5^(1))

5^((-2 )+ (-1) )

5^(-3)

We know a^(-2)= 1/ a^2

1/ 5^(3)
