Sketch a right
triangle having adjacent side(A) is given as “3”, hypotenuse side (H) is “x”
and assigning angle “a” as the angle between A and H. Using Pythagorean theorem,
you will get “square root of x-squared minus 9” as the opposite side (O). Using
SOH CAH TOA function, and since secant is the reciprocal of cosine, sec(a) =
x/3. Thus, a = arcsec(x/3). The remaining expression tan(a) is Opposite side
over Adjacent side which is equal to “square root of x^2 - 9” over "3". Therefore, the
algebraic expression would be: tan(arcsec(x/3)) = “sqrt (x^2 -9)” /3. Different answers can be made depending on which side you consider the “3” and “x”.
Answer:
D
Step-by-step explanation:
All we need to know is that there are 2 PASTRIES, this makes it to where we can exclude any equation multiplying against two tea cups. Thus making D the only answer correct.

Explanation:
The three Reasons tell you what to look for to put in the Statement blank.
1. We are given that RE = 2AR and RT = 2GR.
2. The only vertical angles in the figure are ...
∠GRA ≅ ∠TRE
3. Using the given relation between the sides, we can write the proportion ...
RE/RA = RT/RG = 2
It is nice, though maybe not absolutely essential, to write the segment names in order of corresponding vertices.
4. Having shown that two sides are proportional and the angle between them is congruent, we can claim similarity using the SAS Theorem.
28 degrees is the answer , 76+76= 152, 180-152+ 28
8^2+7^2=c^2, 64+49=c^2, 113=c^2, c=10.63
