Answer:
9.7 rounded to 10
Step-by-step explanation:
I'm pretty sure 10 would be the answer, because since they are similar triangle you would cross multiply. So you would do 
, you would the cross multiply 23×17 and 40×X. You would then have 40X=391, so you would divide 391÷40, so X=9.7 or 10

Answer: Choice E) 1</h3>
Work Shown:
Therefore, 
is an identity for all values of β for which the original expression is defined. I used the difference of squares rule for the 2nd step. Then I applied the pythagorean trig identity for the 3rd step.
1.) It would be: 27/36 = 3/4 = 0.75
2) 3/13 = 0.23
3) 1/11 = 0.09
