Review the proof.A 2-column table with 5 rows. Column 1 is labeled step with entries 1, 2, 3, 4, 5. Column 2 is labeled Statemen

t with entries Tangent (StartFraction theta Over 2 EndFraction) = StartRoot StartFraction 1 minus cosine (x) Over 1 cosine (x) EndFraction EndRoot, Tangent (StartFraction theta Over 2 EndFraction) = (StartFraction StartRoot 1 minus cosine (x) EndRoot Over StartRoot 1 cosine (x) EndRoot EndFraction) (StartFraction question mark Over StartRoot 1 cosine (x) EndRoot EndFraction), Tangent (StartFraction theta Over 2 EndFraction) = StartFraction StartRoot 1 minus cosine squared (x) EndRoot Over 1 cosine (x) EndFraction, Tangent (StartFraction theta Over 2 EndFraction) = StartFraction StartRoot sine squared (x) EndRoot Over 1 cosine (x) EndFraction, Tangent (StartFraction theta Over 2 EndFraction) = StartFraction sine (x) Over 1 cosine (x) EndFraction.Which expression will complete step 2 in the proof?

Sounds as tho' you have an isosceles triangle (a triangle with 2 equal sides).  If this triangle is also a right triangle (with one 90-degree angle), then the side lengths MUST satisfy the Pythagorean Theorem.

Let's see whether they do.

8^2 + 8^2 = 11^2  ???
 64    + 64 = 121?  NO.  This is not a right triangle.

If you really do have 2 sides that are both of length 8, and you really do have a right triangle, then:

8^2 + 8^2 = d^2, where d=hypotenuse.  Then 64+64 = d^2, and 

d = sqrt(128) = sqrt(8*16) = 4sqrt(8) = 4*2*sqrt(2) = 8sqrt(2) = 11.3.

11 is close to 11.3, but still, this triangle cannot really have 2 sides of length 8 and one side of length 11.

I have a few questions!<br> a) x−1.27=4.09<br> b) 2.3−y=2.301<br> c) t+3.04=14.3<br> d) 1.1+k=5.67

Answer:

a.)  x = 5.36

b.)  y = - 0.001

c.)  t =  11.26

d.)  k =  4.57

Step-by-step explanation:

a) x−1.27=4.09

b) 2.3−y=2.301

c) t+3.04=14.3

d) 1.1+k=5.67

Solving. right?

a.)  x = 4.09 + 1.27 = 5.36

b.)  y = 2.3 - 2.301 = - 0.001

c.)  t = 14.3 - 3.04 =  11.26

d.)  k = 5.67 - 1.1  =  4.57
