Answer:

Step-by-step explanation:
In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse, or longest side, of the triangle.
In the given triangle, the adjacent side to angle P is marked as
and the hypotenuse of the triangle is
. Therefore, we have:

20:30 so it becomes 2:3 as a fraction it would be 2/3. a fraction is basically a ratio.
Bro how could you not know this it’s 4
Divide the figure into a triangle on the left and a rectangle on the right. You know the side lengths of the rectangle are 3 x 10, so multiply to get the area of the rectangle. Next, find the area of the triangle. The area of a triangle is given by 1/2bh, where b is the base and h is the height. Because you know the short side of the rectangle is 3, subtract 3 from 5 to get the base of the triangle. then multiply that by 10, the height, and divide by 2 to get the area of the triangle. Then just add up the area of the triangle and the area of the rectangle to get your answer :)
7X-4=6X-4-X
7X-6X+X=0
2X=0
X=0
