Angle ADC is a linear pair ( 180° )
=> BDE = 68°
Similarly,
BCE is a linear pair or straight line.
BEC = BED + DEC
=> 180° = BED + 126°
=> BED = 180° - 126°
=> BED = 54°
As we know that Sum of angles of triangle is 180° .
m + 68° + 54° = 180°
=> m + 122 = 180°
=> m = 180° - 122°
=> m = 58°
<u>The value of m is 58</u>° .
Answer:
Step-by-step explanation:
Let's find the answer by using the arc length formula which is:
First, let's find dy/dx which is:
y=4x-5
y'=4*(1)-0
y'=4, now let's use the formula:
Now, using the distance formula we have:
So we have two points (-1, -9) and (3, 7) so:
Notice both equations gave the same length .
