Write the expression as the sine, cosine, or tangent of an angle. (6 points) cos 94° cos 37° + sin 94° sin 37°
klasskru [66]

Answer:

cos57 = 0.5446

sin57 = 0.8387

tan57 = 1.5399

Step-by-step explanation:

Given

cos 94\° cos 37\° + sin 94\° sin 37\°

Required

Determine the

<em>- sin</em>

<em>- cosine</em>

<em>- tangent</em>

of an angle

The given expression can be represented as follows;

cosAcosB + sinAsinB

Where A = 94 and B = 37

In trigonometry:

cosAcosB + sinAsinB = cos(A - B)

Substitute 94 for A and 37 for B

cos(A - B) = cos(94 - 37)

cos(A - B) = cos(57)

Hence, the angle is 57;

<em>Since 57 is not a special angle; I'll solve using a calculator</em>

cos57 = 0.5446

sin57 = 0.8387

tan57 = 1.5399

- 2/3 (x+12)+2/3 x=-5/4 x+2
bogdanovich [222]

We will have the following:

-\frac{2}{3}(x+12)+\frac{2}{3}x=-\frac{5}{4}x+2\Rightarrow-\frac{2}{3}x-8+\frac{2}{3}x=-\frac{5}{4}x+2\Rightarrow-\frac{2}{3}x+\frac{2}{3}x+\frac{5}{4}x=2+8\Rightarrow\frac{5}{4}x=10\Rightarrow5x=40\Rightarrow x=8

So, the value of x is 8.
