Answer:
(a) 46°
(b) 86°
Step-by-step explanation:
When the secants cross externally (figure a), the angle where they cross is half the difference of the subtended arcs.
When they cross internally (figure b), the angle is half the sum of the subtended arcs.

<h3>(a)</h3>
Half the difference of arcs VW and VX is ...
∠VYW = 1/2(160° -68°) = 46°
m∠VYW = 46°
__
<h3>(b)</h3>
Half the sum of arcs AB and CD is ...
∠CED = 1/2(arc AB +arc CD)
2×∠CED = arc AB +arc CD . . . . . multiply by 2
2×∠CED -arc AB = arc CD . . . . . subtract arc AB
arc CD = 2×85° -84° = 86°
m arc CD = 86°
The answer should be y=3x-3 hope this helps!
Answer:
19
Step-by-step explanation:
Rearranging the number in ascending order,
12,15,17,19,19,20,24,26
Median = The average of the 4th and 5th number
Given :
Distance covered by object , D = 63 cm .
Time taken to cover distance D , t = 2 days .
To Find :
The speed of object in m/s .
Solution :
First we will convert all units into m and hours .
D = 63 cm = 0.63 m .
.
Now , speed is :
Hence , this is the required solution .
Answer:
Opposite sides of a parallelogram are parallel (by definition) and so will never intersect. The area of a parallelogram is twice the area of a triangle created by one of its diagonals. The area of a parallelogram is also equal to the magnitude of the vector cross product of two adjacent sides.
