Answer:
So new price of per liter petrol is 96 p
Step-by-step explanation:
Given:
Price of Petrol = 80p
Increase in price = 20%
To find :
Cost per liter = ?
Solution:
As it is given that old price of petrol is 80p
Increase in price = 20 % of Old Price
New Price = Old price + Increase in price
Now first we will find increase in price
Increase in price = 20 % of 80
It could be written as
=
=
Increase in price = 16 p
New price = old price + original price
= 80 p + 16 p
= 96 p
So new price of per liter petrol is 96 p
In ∆ABC, AC = 15 centimeters, m B = 68°, and m C = 24°. What is BC to two decimal places?
Answer provided by our tutors
we are given two angles and one side (which is not between the angles)
we find the angle m A by using 'angles of a triangle add to 180°':
m A = 180 - (m B + m C)
m A = 88°
we can find side BC by using The Law of Sines:
BC/sin A = AC/sin B
BC/sin 88° = 15/ sin 68°
BC = 15*sin 88° / sin 68°
BC = 16.19 cm.
