Answer:
This is a right angle.
Step-by-step explanation:
As you can see below, the angle specified is 90 degrees. That is a right angle.
Take the root of both sides, and solve.
x = 2i sqrt 2, -2i sqrt 2.
Based on the right angle triangle and the given parameters, cos K = 5/13
<h3>Trigonometric ratios</h3>
- sin = opposite / hypotenuse
- cos = adjacent / hypotenuse
- Tan = opposite / adjacent
Given parameters:
- Hypotenuse = 13
- Adjacent = 5
- Opposite = 12
Therefore,
cos K = adjacent / hypotenuse
cos K = 5/13
