<h2>Answer:</h2>

The statements which are true are:

  • a\sin B=b\sin A
  • \dfrac{a}{\sin A}=\dfrac{b}{\sin B}
  • \dfrac{b}{\sin B}=\dfrac{c}{\sin C}
<h2>Step-by-step explanation:</h2>

In Trigonometry, the Law of Sine relates the length of sides of a triangle to the angle of a triangle.

According to this law if a,b and c are the sides of a triangle and A,B and C  respectively are opposite angles to the side.

Hence, we have:

\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}

i.e. we have:

\dfrac{a}{\sin A}=\dfrac{b}{\sin B}

This could also be given by:

a\sin B=b\sin A

\dfrac{b}{\sin B}=\dfrac{c}{\sin C}

Answer:

See below.

Step-by-step explanation:

The law of sines is usually written as a / sin A = b / sin b == c / sin C    where a is the side opposite angle A ,etc.

The first equation is true because it is obtained by cross multiplying

a / sin A = b / sin B,  therefore   b sin A = a sin B.

The second one is not true.

The third and fourth are both true.

Damm [24]

Answer:

  6.5e^(i·(-157.38°)) ≈ 6.5e^(-2.7468i)

Step-by-step explanation:

A suitable calculator can find the value of this ratio for you.

  ((2+3i)/(1-i))² = -6 -2.5i ≈ 6.5∠-157.38° ≈ 6.5e^(-2.7468i)

The second attachments shows the calculator set to radian mode for the angle measure.

The length of the sides of a triangle are three consecutive integers. If the perimeter is 87, find the dimensions of the triangl
nadezda [96]
You can divide 87 by 3 which is 29, so each angle will be 29 degrees.
Since they are consecutive, that means they will all measure the same.

Hope this helps! :)
