Answer:
The approximate value of the area is
Step-by-step explanation:
we know that
The area of the circle (landing pad) is equal to
we have
substitute
----> exact value of the area
Find the approximate value
assume
------> approximate value of the area
Answer:
Step-by-step explanation:
question no . 5
ratio of angle L
take angle as reference angle
using cos rule
cos L = base / hypotenuse
= 4/5
ratio of angle N
take angle N as reference angle
using sin rule
sin N = opposite / hypotenuse
= 4/5
for measure of angle L
cos L = 4/5
cos L = 0.8
L =
L = 36.9
for meanure of angle N
sin N = 4/5
sin N = 0.8
N =
N = 53.1
