Answer:
Below
Step-by-step explanation:
sin(2x) = 2 ×cos(x)× sin(x)
● sin(x) = 2 × cos(x) × sin(x)
● 2 × cos(x) = 1
● cos (x) = 1/2
So we can deduce that:
● x = Pi/3 + 2*k*Pi
● or x = -Pi/3 + 2*k*Pi
K is an integer

Step-by-step explanation:
<u>Step 1: Define</u>
P = x + y
x = 11
y = 6
<u>Step 2: Evaluate</u>
- Substitute: P = 11 + 6
- Add: P = 17
And we have our final answer!
Both angles should be 90degrees
