Answer:
2/b
Step-by-step explanation:
a/b=3b
a=3b*b
a=3b^2
6b/a=6b/(3b^2)=2/b
The answer is C
explanation:
In all triangles the interior angles add up to 180 degrees. the top angle of this triangle is 90 degrees and 180-90=90, so the bottom 2 angles add up to 90. They are symmetrical, so you can just divide 90 by 2 who is 45 and you have to it answer.

Answer: OPTION B.
Step-by-step explanation:
The missing figure is attached.
For this exercise you need to use the Pythagorean Theorem. This is:
Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.
In this case you can identify in the figure the triangle PRS, so the diagonal PR is the hypotenuse of the triangle PRS.
Then you can say that:
Therefore, knowing these values, you can substitute them into :
Finally you must solve for PR in order to find its value. This is:
Answer:
tanx·secx
Step-by-step explanation:
To simply this, you can begin by factoring sin x out of the numerator to become:
Now, using Pythagorean Trig Identities, we know that sin²x+cos²x equals 1. We can substitute this to make the equation become:
First of all, we can convert to tanx. However, we have a remaining which, using reciprocal identities, will become sec x.
Finally, we get our answer as tanx·secx.
