Answer:

x = 12

y = 16.97 or 17

Step-by-step explanation:

\sin \: 45 \degree =  \frac{12}{y}  \\  \\   \frac{1}{ \sqrt{2} } =  \frac{12}{y}  \\  \\ y = 12 \sqrt{2}  \\  \\ y = 12 \times 1.414 \\  \\ y = 16.968 \\  \\ y \approx \: 16.97\approx \: 17 \:  \\  \\  \\  \tan \: 45 \degree =  \frac{12}{x}  \\  \\   1 =  \frac{12}{x}  \\  \\ x = 12

Answer:

x=12

x=12√2

Step-by-step explanation:

tan45=12/x

x=12

y=√12^2+12^2

y=√144+144

y=√288

y=16.97

Find the exact values of the indicated trigonometric functions. Write fractions in lowest terms.
vodka [1.7K]

For this case we have that by definition of trigonometric relations of a rectangular triangle, that the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. While the tangent of the same angle is given by the leg opposite the angle on the leg adjacent to the angle.

Then, according to the figure we have:

sin (B) = \frac {7} {25} = 0.28\\tg (B) = \frac {7} {24} = 0.2917

Answer:

sin (B) = \frac {7} {25}\\tg (B) = \frac {7} {24}

A student says that the​ x-intercept of a line is ​(0,-10,​). Is the student​ correct? Explain.
nataly862011 [7]

Answer:

Yes, the student is correct

Step-by-step explanation:

Given

(0,-10)

Required

Does it represent the x intercept

At the x intercept, the value of x is 0.

So, the function (x,y) becomes (0,y)

(0,-10) can be compared to (0,y)

Hence, the student is correct
