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.
Answer:
I do not see anything that matches what I got. I got x=14.2
Step-by-step explanation:
5x+9=80
5x=71
x=14.2
Answer:
What choice and what expression
Step-by-step explanation:
Answer:
x = 7 is repeated twice.
Hence, there is NO MORE unique input. We can not have repeated inputs.
Thus, the relation is NOT a function.
Step-by-step explanation:
Given the relation
- {(6, 8), (7, 10), (7, 12), (8, 16),
(10, 16)}
We know that a relation is a function that has only one output for any unique input.
As the inputs or x-values of the relations are:
at x = 6, y = 8
at x = 7, y = 10
at x = 7, y = 12
at x = 8, y = 16
at x = 10, y = 16
If we closely observe, we can check that there is a repetition of x values.
i.e. x = 7 is repeated twice.
Hence, there is NO MORE unique input. We can not have repeated inputs.
Thus, the relation is NOT a function.
