Step-by-step explanation:
Quadrilateral ABCD is inscribed in a circle.
Opposite angles of a Quadrilateral are Supplementary.

First you need to get all variables on one side. You do that by multiplying the reciprocal of the fraction to everything.
N(5/1) x 1/5(5/1)=2/15(5/1)
5n=2/15 x 5/1
Then solve the multiplication problem
5n= 10/15
Then you should reduce the fraction
5n=2/3
Then divide both sides by 5
5n/5=N
2/3 divided by 5 =2/15
N=2/15
The third one
U solve from left to right and when two negatives are next to each other it turns to a plus.
- Initial velocity=u=0m/s
- Distance=s=150m
- Time=t=10s
- Acceleration=a
Using second equation of kinematics






Using newtons second law



A= (b sin A)/ sinB
a= (15.8 sin29)/ sin36
a= 13.03 cm
