Answer:

\text{The length of third side is }\sqrt7 units

Step-by-step explanation:

Given that a triangle has two sides of length 2 and 3 and that the angle between these two sides is 60°.

Let b=2 units and c=3 units

we have to find the length of the third side of the triangle.

By law of cosines

a^2=b^2+c^2-2bc\cosA

where A is the angle between the side b and c

a^2=2^2+3^2-2(2)(3)\cos60

a^2=4+9-6=7

a=\pm\sqrt7

Length cannot be negative

∴ a=\sqrt7 units

Option B is correct.

Solve this question <br>a=7+3​
mr Goodwill [35]

Answer:

<h2>10</h2>

Step-by-step explanation:

<em>The answer is 10 because 7 + 3 equals 10!</em>

<em></em>

<em>This can be proven by adding 7 + 3 or by subtracting in a certain way.</em>

<em>7 + 3 = ?</em>

<em>7 + 1 = 8</em>

<em>7 + 2 = 9</em>

<em>7 + 3 = 10</em>

<em></em>

<em>You can show more work by subtracting your answer or 10 in this case, which means that you subtract 7 by 10 or 3 by 10, either way is ok.</em>

<em></em>

<em>If you subtract 7 by 10, ( 10 - 7 ) then you get 3</em>

<em>If you subtract 3 by 10, ( 10 - 3 ) then you get 7</em>

<em>If the number you subtracted matches the number that you didn't subtract, then your answer is correct.</em>

<em></em>

<em>Hope this helps! <3</em>

Please answer this correctly without making mistakes

Answer:

so first convert to fraction so

9 3/4 = 39/4

so it was spread among 3

so this is division so you do 39/4 divided by 3

so you keep switch flip

which is  39/4 *1/3

answer is 13/4
