Find the percentage error |sinθ - θ|/sin(θ)*100 this approximation introduces for an angle of 0. 020 radians.

Elza [17]

Considering the given angle and the given formula, it is found that the percentage error for an angle of 0.02 radians is of 0.0067%.

<h3>What is the percentage angle for an angle?</h3>

For an angle $\theta$ , it is given by the following formula:

$P = 100\frac{|\sin{\theta} - \theta|}{\sin{\theta}}$

In this problem, the angle is of $\theta = 0.02$ , hence:

$P = 100\frac{|\sin{0.02} - 0.02|}{\sin{0.02}}$

$P = 0.0067$

The percentage error for an angle of 0.02 radians is of 0.0067%.

X + 5y = 8<br> -x + 2y = -1<br> How is this solved?

Oksi-84 [34.3K]

Add both the equations together to eliminate x

x+5y=8
-x+2y=-1

7y=7
y=1

Now fill in y into the original equation

x+5(1)=8
x+5=8
x=3

Now you can check by filling x and y into the second equation.

-(3)+2(1)=-1
-3+2=-1
-1=-1

So your answer will be (3, 1)
