Hypotenuse = √[ (3)^2 + (-2)^2] = √13
sin(x) = -2/√13
csc(x) = 1 / sin(x) = - √13 / 2
cot (x) = 3 / (-2) = -3 / 2
Answer:
2 5/12
Step-by-step explanation:
You have to add 1 3/4 and 2/3 together. You find the common denominator, 12, and convert the fractions. 1 3/4 becomes 1 9/12 and 2/3 becomes 8/12. 1 9/12 + 8/12 is 1 17/12. 1 17/12 simplified is 2 5/12.
Answer:
radius = 12.3 cm
Step-by-step explanation:
The formula to find the circumference of a circle:
Circumference = 2 × π × r
77 = 2 × π × r
r =
r = 12.3 cm (in 3 significant figures)
Sustitute the value of the variable inot the equation and simply and you get 0.5
