Answer:
a = 180° -73°
b = 73°
c = 180° -73°
Step-by-step explanation:
73° and b are vertical angles, so are congruent (equal).
a and c are equal to each other and each is a linear angle with 73°, so is the supplement of that angle. You could write the equation as ...
a + 73° = 180°
but I prefer to get to the heart of it. The values of a and c are the difference between 180° and 73°.
Answer:
I think you need to multiply 12 and 7 and then cut that in half
Answer:
5.40 is not the same as 7.00
Step-by-step explanation:
Given,
Rate of free fall = 216 km/h
Solution,
km/h to m/s is converted as follows :

So, the rate of fall is 60 m/s.
If t = 20 s
Assume, initial velocity = 0
It will move under the action of gravity.
Using equation of motion,

Hence, this is all for the solution.
