Let A be the angle of 79 degrees
B be the angle of (5y-4) degrees
C be the angle of (x+5) degrees
D be the angle of (9z-7) degrees
According to the property of parallelogram
Opposite angles are equal
We get, angle A = angle C
Since angle A = 79 degrees
And angle C = (x+5) degrees
We get, x+5=79
=> x=79-5=74.
Angle B = Angle D
(5y-4)=(9z-7)
Since there’s two variables here, we can’t use the property of “opposite angles are equivalent”
We have to use another property which is adjacent angles are equal
Therefore, we can find angle D
Angle D + Angle A=180
=> 9z-7 =180-79
z=108/9
z=12
Since (5y-4)=(9z-7)
Substitute z=12 in
We get, 5y-4=101
y= 105/5
y= 21
Therefore, x=74, y=21 and z=12.
Answer:
B and C
Step-by-step explanation:
D. 50
Thats because below sea level would be -50
so the oppisite would be 50 which is 50 feet above sea level
The coordinates of other endpoint S is (3, 2)
<h3><u>Solution:</u></h3>
Given that midpoint of RS is M
Given endpoint R(23, 14) and midpoint M(13, 8)
To find: coordinates of the other endpoint S
<em><u>The formula for midpoint is given as:</u></em>
For a line containing containing two points 
and 
midpoint is given as:
Here in this problem,
m(x, y) = (13, 8)
Substituting the given values in above formula, we get
Comparing both the sides we get,
Thus the coordinates of other endpoint S is (3, 2)
The value of this equation is: 4
Answer: 4
