Evaluate the six trigonometric functions of the angle 0

Alla [95]

# Sin θ = 9/15.

# Cos θ = 12/15.

# Cosec θ = 15/9.

# Sec θ = 5/4

Step-by-step explanation:

$by \: using \: pythagorian \: triplets$

${a}^{2} + {b}^{2} = {c}^{2}$

${9}^{2} + {12}^{2} = {c}^{2}$

$81 + 144 = {c}^{2}$

$225 = {c}^{2}$

$c = 15.$

$\sin θ = \frac{9}{15}$

$\cos θ = \frac{12}{15} = \frac{4}{5}$

$\csc θ = \frac{15}{9}$

$\secθ = \frac{5}{4}$

HELP PLS Solve for x x=[?] 3x + 2 6x - 20

Sloan [31]

Step-by-step explanation:

Remember that the sum of angles on a straight line are supplementary. (180°)

Therefore 3x + 2 + 6x - 20 = 180.

=> 9x - 18 = 180

=> 9x = 198

=> x = 22.

How to find the diameter if you have the circumference

Ivanshal [37]

Answer:

Solve the equation for the diameter of the circle, d= C/π. In this example, "d = 12 / 3.14." or "The diameter is equal to twelve divided by 3.14." Divide the circumference by pi to get the answer. In this case, the diameter would be 3.82 inches
