Answer:
a). m∠AED = 70°
b). x = 10°
Step-by-step explanation:
a). Quadrilateral ABDE is a cyclic quadrilateral.
Therefore, by the theorem of cyclic quadrilateral,
Sum of either pair of opposite angle is 180°
m(∠AED) + m(∠ABD) = 180°
m(∠AED) = 180° - 110°
m(∠AED) = 70°
Since, ∠AED ≅ ∠EAD
Therefore, m∠AED = m∠EAD = 70°
b). By triangle sum theorem in ΔABD,
m∠ABD + m∠BDA + m∠DAB = 180°
110° + 40° + m∠DAB = 180°
m∠DAB = 180° - 150°
m∠DAB = 30°
m∠BAE = m∠EAD + m∠BAD
= 70° + 30° = 100°
By angle sum theorem in ΔACE,
m∠EAC + m∠AEC + m∠ACE = 180°
100° + 70° + x° = 180°
x = 180° - 170°
x = 10°

Answer:
Multiply row 1 by .
Step-by-step explanation:
The augmented matrix of the system of linear equation is described below:
Where , if we need to create , we need to multiply row 1 by , that is to say:
Hence, the correct answer is: Multiply row 1 by .
The
s then cancel, leaving you with the
term.
If it's not clear what I did above, consider the substitution
and
. Then
Her walk rate is 3.33 meter per sec you find this by dividing meters by seconds
Then you multiply this 3.33 by 50 you get 166.5 meters
d=t3.33 is the equation
