Answer:
A
Step-by-step explanation:
A good trick for trigonometric functions is to remember SOHCAHTOA:
Sin=<u>O</u>pposite over <u>H</u>ypotenuse
Cos=<u>A</u>djacent over <u>H</u>ypotenuse
Tan=<u>O</u>pposite over <u>A</u>djacent
The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.
So in this case, the sin of angle A (opposite over hypotenuse) would be
and cos A (adjacent over hypotenuse) would be
.
I hope this helps!
so x^2 + 3x + 2 = 2x+3
or x^2 + x = 1
After that just use the a quadratic equation formula
Answer:
f = 15
Step-by-step explanation:
15 + 6f = 7f
subtract 6f from each side
15= 1f
15=f
Answer:
Step-by-step explanation:
Do you mean
divide 6300 between two persons in the ratio 2 to 5?
If so, then there will be a total of 7 parts
6300/7 = 900
2(900) = 1800
5(900) = 4500
