Answer:

Step-by-step explanation:

It is a parallelogram so the opposite angles are the same.

All angles sum to 360 degrees.

This means that the adjacent angles sum to 180 degrees.

4a + 11 + 9a = 180 = 13a + 11

13a = 169

a=13

Six times the sum of a number and 8 is 2

ehidna [41]

6(n+8)=2
6n + 48 = 2
6n + 48 - 48 = 2 - 48
6n = -46
N = -46/6
N = -7 2/3

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%.
