Dude this is simple just x>0
Answer:
D look up the question on quizlet to get all of your answers to your lesson :)
Step-by-step explanation:
9√2 is squared first.
so its 162.
now according to Pythagoras theorem,
x2+x2=162
2x^2= 162
x^2= 162÷2
x^2= 81
x= √81
x=9
1) 32*10^4 is not written in scientific notation because the first factor is not a number betweem 1 and 10.
3.4 * 10^5 is the same number written in scientific notation.
2) 2.01x10^-5 is written in scientific notation.
Answer:
The angle measures are 53.5° and 36.5°.
Step-by-step explanation:
We can create a systems of equations, assuming x and y are the angle measures.
Since the two angles are complementary, their angle measures will add up to 90.
x + y = 90
x - y = 17
We can now use the process of elimination, and end up with:
2x = 107
Dividing both sides by two gets us
x = 53.5
Substituting this value into an equation will get us y
53.5 + y = 90
y = 36.5
Hope this helped!
