Steps

99-3(15-(2+1))

3(15-(2+1))=36

add the numbers: 2+1=3

=3(15-3)

Subtract the numbers: 15-3=12

=3 times 12

multiply the numbers: 3 times 12=36

=36

=99-36

subtract the numbers: 99-36=63

=63

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%.
