Let

A( 5.0,2.8) B( -2.8,5.1)

we know that

The formula to find the distance between two points is equal to

d=\sqrt{(y2-y1)^{2} +(x2-x1)^{2}}

substitute in the formula

d=\sqrt{(5.1-2.8)^{2} +(-2.8-5)^{2}}

d=\sqrt{(2.3)^{2} +(-7.8)^{2}}

d=\sqrt{66.13}

d=8.13\ cm

therefore

<u>the answer is</u>

the distance between these points is 8.13\ cm

How many distinct triangles can be formed for which m∠X = 51°, x = 5, and y = 2? zero one two
Vitek1552 [10]
From the law of sines, we have:

\displaystyle{ \frac{\sin \angle X}{x}= \frac{\sin \angle Y}{y}, 

where x and y are the sides opposite to angles X and Y, respectively.


Substituting the known values, we have:



\displaystyle{ \frac{51^{\circ}}{5}= \frac{\sin \angle Y}{2}, thus

                           \displaystyle{ \sin \angle Y=\frac{\sin 51^{\circ}}{5}\cdot2\approx \frac{0.777}{5}\cdot2=0.31.


Using a calculator, we can find that arcsin(0.31)=18 degrees, approximately.

We know that sine of (180-18)=162 degrees is also 0.31. But 162 and 51 degrees add up to more than 180 degrees.

Thus, there is only one triangle that can be formed under these conditions.
