Answer:
m∠BCD = 140°
Step-by-step explanation:
ABCD is cyclic quadrilateral. A property of cyclic quadrilateral states that the opposite angles of it sum up to 180°. Here:
m∠A + m∠C =180° and m∠B + m∠D = 180°
So, m∠A + m∠C =180°
m∠A = 40° (given in the question)
40° + m∠C = 180°
m∠C = 180° - 40° = 140°
∴m∠C = m∠BCD = 140°
The vertical distance is 5 + 8 = 13
the horizantal distance is 3 +3 = 6
then just do pythag therom
6^2 + 13^2 = c^2
205 = c^2
<span>√205 = c

I would’ve gone with the same choice so I think it’s right!!

Answer:
Option C) The first equation is y= 2/3x-4 when written in slope-intercept form .
Step-by-step explanation:
We have

The first equation is in Standard form .
Convert to slope Intercept form .
Isolate the Variable y .

Divide by 3 both sides .


The second equation is in slope Intercept form .
Convert to standard form
Multiply by 5 both sides to remove the fraction .


<h3><u>Verify each statement :- </u></h3>
<h3>• case A) Both equations are in slope-intercept form.</h3>
- Because only the second equation is in slope -intercept form
<h3>• case B) Neither equation is in slope-intercept form .</h3>
- Because, the second equation is in slope -intercept form
<h3>• case C) The first equation is y= 2/3x-4 when written in slope-intercept form</h3>
<h3>• case D)The second equation is 3x+5y=10 when written in slope-intercept form.</h3>
- Because, the second equation is 3x+5y=10 when written in standard form .
