Answer:
cos = adjacent of angle A / hypotenuse
Step-by-step explanation:
cos = adjacent of angle A / hypotenuse . . . . . . . . . . . .
Let's say the Height of the triangle is 4 cm., the Base is 3 cm, and the Hypotenuse is 5 cm. If the top angle was angle A then the value would be 4/5. Because the Height is adjacent to angle A and the Hypotenuse is 5 cm.
