What are the necessary conditions to apply the SAS triangle congruence theorem?
Gala2k [10]

Answer:

The correct answer is 2. An angle and the two sides collinear with the angles race are congruent to the corresponding parts of another triangle.

Step-by-step explanation:

The Side Angle Side postulate (often abbreviated as SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.

An included angle is an angle formed by two given sides.

So, the correct answer is 2. An angle and the two sides collinear with the angles race are congruent to the corresponding parts of another triangle.

Anyone know what the answer is???(sorry if it’s unclear)
Sergio [31]

The laws of exponents I will be using are:

(x^y)^z = x^{yz}, and x^y \cdot x^z = x^{y+z}.

For the first part, (15^3)^3 \cdot 15^{-6} = 15^9 \cdot 15^{-6} = 15^3.

For the second part, 15 \cdot (15^3)^2 \cdot (15^{-5})^2 = 15 \cdot (15^6) \cdot (15^{-10}) = 15^{1+6-10} = 15^{-3} = \frac{1}{15^3}.

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} }
