Answer:
Slope of JK = -4/5
Step-by-step explanation:
We know that GHJK is a parallelogram. If GHJK is a parallelogram then the sides of parallelogram will be:
GH, HJ, JK, GK
Hence the opposite sides will be:
GH and JK
HJ and GK
We know that opposite sides of parallelogram are parallel to each other and the slopes of parallel lines is equal.
So the slope of GH and JK will be equal.
And slopes of HJ and GK will be equal.
As we are given the slope of GH which is -4/5, the slope of JK will also be -4/5 because both lines are parallel.
Step-by-step explanation:
1..x=110/2. ( inscribed angle is half of central angle)
2..given,
in triangle DFE
angleDFE=angle DAE ( inscribed angle on same arc are equal)
angle DFE=55°
angle EDF= angle FED (base angle of isosceles triangle r equal)
now,
angle EDF+angleDFE+angle FED =180°{ sum of angle of triangle)
z+z+55=180°
2z=180-55
z=125/2
z=62.5°
3.. y=90°{ angle at circumference of circle by center is 90°}
hope it helps.
