Two significant Figures I believe because you want to go with the least amount of sig figs that are already in your problem which would be 2 in 7500 because the zeros are not significant
Answer:
-0.1846
Step-by-step explanation:
-5/13 + 1/5 = -0.1846
X^4 - 3x^2 + 2
= (x^2 - 1)(x^2 - 2)
Note that x^-1 is the difference of 2 squares:-
= (x + 1)(x - 1)(x^2 - 2) Answer
Get as close to the perfect square, which you should have memorized. then divide the number by the perfect square. average the answers (perfect square and quotient) by adding them and diving by 2
ANSWER:
m∠1 = 60°
m∠2 = 60°
m∠3= 120°
EXPLANATION:
The purple arrows indicate that side are parallel, so we know that that triangle NMP is the same as triangle NOP. If they are they same then we know that ∠1 and ∠2 equal 60° since the opposing angles equal 60°.
For ∠3 we look at the opposing angle and now know it is 60°. Since ∠3 and the opposing angle make a straight line which equals 180°. We can figure out ∠3 by subtracting 60 from 180 = 120°.
