Write an equation for the line containing (7,7) and (2,-3).
drek231 [11]

Answer:

y = 2x - 7

Step-by-step explanation:

To find the line equation we assume that its form is y = m*x + b. Where m is the slope and b is the independent variable that intercepts the Y axis.

If we have two points as P1=(x1,y1) and P2=(x2,y2) we can use the slope formula as:

m = (y2-y1)/(x2-x1)

The points given are P1=(7,7) and P2=(2,-3), then the using the slope formula we obtain:

m = (-3-7)/(2-7)

m = (-10)/(-5)

m = 2

By now the equation is y = 2x + b. To find the value of b we have to replace in the equation any point, in this case i am using P2:

-3 = 2*(2) + b

-3 = 4 + b

-3 -4 = b

-7 = b

Therefore the equation of the line is:

y = 2x - 7

In ABC, BC=4 cm, angle b=angle c, and angle a=20 degrees, what is ac to two decimal places
zubka84 [21]

Answer:

Therefore,

AC=11.52\ cm

Step-by-step explanation:

Given:

In ΔABC, BC=4 cm,

angle b=angle c, and

angle a=20°

To Find:;

AC = ?

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

\angle a+\angle b+\angle c=180\\\therefore 2m\angle b =180-20=160\\m\angle b=\dfrac{160}{2}=80\°

We know in a Triangle Sine Rule Says that,  

In Δ ABC,

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

substituting the given values we get

\dfrac{BC}{\sin a}= \dfrac{AC}{\sin b}

\dfrac{4}{\sin 20}= \dfrac{AC}{\sin 80}\\\\AC=11.517=11.52\ cm

Therefore,

AC=11.52\ cm
