Answer:
Step-by-step explanation:
means single part out of 5,
Since, 
Similarly, 
means 2 parts out of 10.
Now we can shade 2 parts out of 10 to show of the given figure.
(As shown in the figure attached)
Since both α and β are in the first quadrant, we know each of cos(α), sin(α), cos(β), and sin(β) are positive. So when we invoke the Pythagorean identity,
sin²(x) + cos²(x) = 1
we always take the positive square root when solving for either sin(x) or cos(x).
Given that cos(α) = √11/7 and sin(β) = √11/4, we find
sin(α) = √(1 - cos²(α)) = √38/7
cos(β) = √(1 - sin²(β)) = √5/4
Now, recall the sum identity for cosine,
cos(x + y) = cos(x) cos(y) - sin(x) sin(y)
It follows that
cos(α + β) = √11/7 × √5/4 - √38/7 × √11/4 = (√55 - √418)/28
15*1.04=15.6
Her new hourly wage will be $15.60
First thing solve for missing side using Pythagorean theorem 20^2=16^2+a^2 then solve for a and we get a=12. Then we can use Toa which means tan=o/a so if we plug in those values we get tan(theta)=16/12
