Answer:

O Sin (53) = 21/29

O Sin (37) = 20/29

Step-by-step explanation:

In a triangle, the sine is opposite over hypotenuse, the cosine is adjacent over hypotenuse, and the tangent is opposite over adjacent.

Answer:

Options 1, 2 and 4 are correct

Step-by-step explanation:

We should determine few things;

Sine = \frac{opposite}{hypotenuse}

Cosine = \frac{Adjacent}{Hypotenuse}

Tangent = \frac{Opposite}{Adjacent}

The values of Opposite and Adjacent vary by the angle given, however Hypotenuse always remains the same, the length opposite to the right angle is hypotenuse.

Now we can say that;

Sin (53) = \frac{opposite}{hypotenuse} = \frac{21}{29}

Sin (37) =  \frac{opposite}{hypotenuse} =\frac{20}{29}

Tan (53) would be \frac{Opposite}{Adjacent} =\frac{21}{20}, not  \frac{20}{21}

Cos (37) = \frac{Adjacent}{Hypotenuse} = \frac{21}{29}

Hope this helps!

Find the value of x.
Rudiy27

Answer:

x=104

Step-by-step explanation:

Angle Formed by Two Secants= 1/2(difference of Intercepted Arcs)

10.5 = 1/2( x-83)

Multiply each side by 2

2* 10.5 = 2*1/2( x-83)

21 = x-83

Add 83 to each side

21+83 = x-83+83

104 =x

56 = h/9<br> k/5 - 10 = 3<br> 3t + 5 =2
uranmaximum [27]

Answer:

h = 504, k = 65, t = -1

Step-by-step explanation:

56 = h/9

h = 56 x 9

h = 504

k/5 - 10 = 3

k/5 = 3 + 10

k/5 = 13

k = 13 x 5

k = 65

3t + 5 = 2

3t = 2 - 5

3t = -3

t = -3/3

t = -1
