Step-by-step explanation:
Given :
1- cosA = 1/2
or, CosA = 1 -1/2
Therefore ; CosA = 1/2 = b/h
According to the Pythagoras theorem,
P = root under h^2 - b^2
= root under (2)^2 - (1)^2
= root under 4 -1
= root 3
Again,
SinA = P/h
= root 3 / 2
Answer:
28.25
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
when we simplify it we get 5-5+5 which equals 5
5.66 (3 significant figures)
We are given eqaution:
, where e the amount of euros and d is the value as U.S. Dollars.
We need to find number of euros for 1 U.S. Dollar.
Plugging d=1 in the given equation
We get

On simplfying , we get

Dividing 17 by 20, we get 0.85.
Therefore, there would be 0.85 euro have the same value as 1 U.S. Dollar.
