Please help with 8 and 10 ..
Natalka [10]

Answer:

8) Parallelogram.

10) Point W.

Step-by-step explanation:

8) Give another name of plane V.

As shown the plane represents A flat shape with 4 straight sides where opposite sides are parallel and also opposite sides are equal in length.

So, plane V represents parallelogram

10) Name a point that is not coplanar with R, S and T.

Coplanar points are the points which all lie in the same plane.

So, as shown:

R, S and T are coplanar points, they all lie in the plane V

So, the point which doesn't lie in the plane V is the point W

So, <u>the point W</u> is not coplanar with R, S and T.

If tanA+cotA=2 then find the value of cosA​
aniked [119]

Answer:

cos A=

\frac{1}{ \sqrt{2} }

Step-by-step explanation:

We know,

cotA=

\frac{1}{ \tan(a) }

Substituting the value of cot A in the given equation, we get

\tan( a)  +  \frac{1}{ \tan(a) }  = 2

\frac{{ \tan }^{2} a + 1}{  \:  \tan(a)  }  = 2

{ \tan }^{2 \: } a \:  + 1 = 2 tan \: a

{ \tan }^{2} a - 2 \tan \: a + 1 = 0

( \tan \: a - 1) {}^{2 }  = 0

\tan \: a - 1 =  \sqrt{0}

\tan \: a = 1

\tan \: a \:  =  \tan \: 45

a = 45

\cos \: a =  \cos \: 45

\cos \: a =   \frac{1}{ \sqrt{2} }
