Answer: Choice C
7 divided by cosec 50 degrees
=====================================
Explanation:
Abbreviations:
sec = secant
cot = cotangent
cosec = cosecant (csc is also a widely used abbreviation)
-----------------
Let the horizontal leg be x
This leg is opposite the angle 50 degrees. The hypotenuse is 7
Opposite = x
Hypotenuse = 7
We'll either use the sine rule or the cosecant (csc) rule
sine = opposite/hypotenuse
cosecant = hypotenuse/opposite
Since "sine" is nowhere to be found in the answer choices, we'll use the cosecant rule
-----------
cosecant = hypotenuse/opposite
csc(angle) = hypotenuse/opposite
csc(50) = 7/x
x*csc(50) = 7
x = 7/csc(50)
This is why the answer is choice C
Answer:
Step-by-step explanation:
Capacity of cylinder =4.25L
So volume of the cylinder=4250
πr^2h=4250
3.14×6.5×6.5×h=4250
132.665h=4250
h=4250/132.665
h=32.035
24:28
52 (total books) minus 24 (fiction books) equals 28 (non fiction books)
Answer:
D
Step-by-step explanation:
I think its D because translation is where something is moved horisontally or vertically without moving orientation.
Answer:
3x+4x=109
Step-by-step explanation:
Si vende los brazaletes amarillos por 3.00 dólares y los verdes por 4 dólares, no sabría cuánto de cada brazalete compró alguien, por lo que necesitaría tener una variable para representar x = número de brazaletes comprados. Y necesitarías variantes para cada color. Para resolver esta ecuación, necesitaría encontrar un número para multiplicar con 3.00 y una variable de 4.00 y luego sumar sus respuestas hasta que sean iguales a 109.00.
