Write expression as a sine or cosine of an angle.<br>cos 94° cos 18° + sin 94° sin 18° ​
MArishka [77]
<h3>Answer:  cos(76)</h3>

=========================================================

Explanation:

The original expression is of the pattern cos cos + sin sin. This pattern matches the second identity in the hint. Specifically, we'll say the following:

cos(A - B) = cos(A)cos(B) + sin(A)sin(B)

cos(A)cos(B) + sin(A)sin(B) = cos(A - B)

cos(94)cos(18) + sin(94)sin(18) = cos(94 - 18)

cos(94)cos(18) + sin(94)sin(18) = cos(76)

----------

We can verify this by use of a calculator. Make sure your calculator is in degree mode.

  • cos(94)cos(18) + sin(94)sin(18) = 0.24192
  • cos(76) = 0.24192

Both expressions give the same decimal approximation, so this helps confirm the two expressions are equal. You could also use the idea that if x = y, then x-y = 0. Through this method, you'll subtract the left and right hand sides and you should get (very close to) zero.

1/6d + 2/3 = 1/4(d-2)
KonstantinChe [14]
\frac{1}{6}d+\frac{2}{3}=\frac{1}{4}(d-2) \\ \\ \frac{d}{6}^{(2}}+\frac{2}{3}^{(4}=\frac{d-2}{4}^{(3} \\ \\ 2d+8=3(d-2) \\ \\ 2d+8=3d-6 \\ \\ 2d-3d=-6-8 \\ \\ -d=-14 \\ \\ \boxed{d=14}

Express the area of this triangle as monomial.
gladu [14]

The formula of an area of a triangle:

A=\dfrac{1}{2}bh

b - base

h - height

We have b = 8x and h = 7x. Substitute:

A=\dfrac{1}{2}(8x)(7x)=(4x)(7x)=28x^2

<h3>Answer: 28x²</h3>

Please help me!
Taya2010 [7]

Answer:

  • x = 12
  • Side = 23 units

Step-by-step explanation:

<u>STU is an equilateral triangle. And:</u>

  • ST = 2x - 1
  • SU = 5x - 37
  • TU = x + 11

<u>All sides are equal. Then take one pair and solve for x:</u>

  • 2x - 1 = 5x - 37
  • 3x = 36
  • x = 12

<u>Substitute x to find the side length:</u>

  • 2x - 1 = 5x - 37 = x + 11 = 23
