Answer:

45 (in centimeters)

Step-by-step explanation:

In ΔVWX we have to find the length of the third side.

When the length of two sides of a triangle and the included angle is given

we can find the length of third side by applying cosine law.

According to cosine law, in a ΔVWX

x^{2} =v^{2}+w^{2} -2vwcosX

                =21^{2}+64^{2}-(2\times21\times64\times cos23)

                =2062.683 (cm)^{2}

              x=45cm (approximating it to nearest integer)

By definition, the slope or gradient of a line describes its steepness, incline, or grade.

Where

m — slope

θ — angle of incline

If the 2 Points are Known

Result

Slope (m) =  

ΔY

ΔX

=  

-1

5

= -0.2

θ =  

arctan( ΔY ) + 360°

ΔX

= 348.69006752598°

ΔX = 5 – -5 = 10

ΔY = -3 – -1 = -2

Distance (d) = √ΔX2 + ΔY2 = √104 = 10.198039027186

Equation of the line:

y = -0.2x – 2

or

y =  

- 1 x

5

– -2

When x=0, y = -2

When y=0, x = -10

Answer:

I think it will be 2/1

Step-by-step explanation:

Its positive I know that, but since the points go right two and up one that should be the slope if i'm not mistaken.
