CD is probably around the 30-40 range? Since it has a 90 degree angle you would subtract that from 180 then that’s 90 and divide by 2?

bekas [8.4K]

Answer:

$y=2\sqrt{3}\ units$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

$AC=BC$ -----> by a 45°-90°-45° triangle

$cos(45\°)=\frac{BC}{AB}$

$BC=ABcos(45\°)$

substitute the values

$BC=(2\sqrt{2})(\frac{\sqrt{2}}{2})=2\ units$

In the right triangle BCD

$tan(60\°)=\frac{BD}{BC}$

substitute the values

$\sqrt{3} =\frac{y}{2}\\ \\ y=2\sqrt{3}\ units$

Write in slope intercept form an equation of the line (1, 2); m = -2

mr Goodwill [35]

Y = 2
X = 1
M = -2
B = ?
y=mx+b
2=-2(1)+b
2= -2 + b
+2 +2
4 = b
Therefore the equation is
y = -2x + 4

Y = 4x – 6 can someone find me the slope for this thanks

Sliva [168]

Answer:

Slope = m = 4

Step-by-step explanation:

y = 4x-6

Comparing this with the standard slope-intercept equation:

$y = mx+b$

Where m is the slope and b is the y-intercept.

So, we get:

Slope = m = 4
