The answer is D because if they don't share an endpi t then it is just two rays

The answer is choice D) Two rays that share the same endpoint

======================================

Here's a full breakdown of the four choices

A. False. If the ray and line aren't touching, then an angle can't be formed.

B. False. Parallel lines never cross. The same issue as before (in part A) comes up.

C. False. Again the rays need to meet up somehow.

D. True. If you have two rays that share the same endpoint, then they form an angle. Think of it like a pair of scissors. Each blade is a ray. The blades are joined at a common node to allow the blades to swing open or closed. You could have an angle formed by line segments or lines, but they would have to intersect in some way.

Pls answer you dont have to show work
Vlada [557]

Answer:

Option C, 6.5

Step-by-step explanation:

<u>Step 1:  Substitute y in the equation 3x - 5y = 22</u>

3x - 5y = 22

3x - 5(-5x + 32) = 22

3x + 25x - 160 + 160 = 22 + 160

28x / 28 = 182 / 28

x = 6.5

Answer:  Option C, 6.5

What's 14 ten thousands + 12 thousand
statuscvo [17]
The answer to this question would be 152,000

In this question, you are given multiple number names and asked to add it. To answer this question, it will be easier to split the sentences into multiple parts like this:
<span>1. "14 ten thousands" mean 14 * 10,000 =140,000
</span><span>2. "12 thousands" mean 12 * 1,000= 12,000
Then, if you add them up it will be: 140,000+ 12,000= 152,000</span>

If sinA=√3-1/2√2,then prove that cos2A=√3/2 prove that
Ivan

Answer:

\boxed{\sf cos2A =\dfrac{\sqrt3}{2}}

Step-by-step explanation:

Here we are given that the value of sinA is √3-1/2√2 , and we need to prove that the value of cos2A is √3/2 .

<u>Given</u><u> </u><u>:</u><u>-</u>

• \sf\implies sinA =\dfrac{\sqrt3-1}{2\sqrt2}

<u>To</u><u> </u><u>Prove</u><u> </u><u>:</u><u>-</u><u> </u>

•\sf\implies cos2A =\dfrac{\sqrt3}{2}

<u>Proof </u><u>:</u><u>-</u><u> </u>

We know that ,

\sf\implies cos2A = 1 - 2sin^2A

Therefore , here substituting the value of sinA , we have ,

\sf\implies cos2A = 1 - 2\bigg( \dfrac{\sqrt3-1}{2\sqrt2}\bigg)^2

Simplify the whole square ,

\sf\implies cos2A = 1 -2\times \dfrac{ 3 +1-2\sqrt3}{8}

Add the numbers in numerator ,

\sf\implies cos2A =  1-2\times \dfrac{4-2\sqrt3}{8}

Multiply it by 2 ,

\sf\implies cos2A = 1 - \dfrac{ 4-2\sqrt3}{4}

Take out 2 common from the numerator ,

\sf\implies cos2A = 1-\dfrac{2(2-\sqrt3)}{4}

Simplify ,

\sf\implies cos2A =  1 -\dfrac{ 2-\sqrt3}{2}

Subtract the numbers ,

\sf\implies cos2A = \dfrac{ 2-2+\sqrt3}{2}

Simplify,

\sf\implies \boxed{\pink{\sf cos2A =\dfrac{\sqrt3}{2}} }

Hence Proved !
