Cosine is adjacent/hypotenuse, so the answer is A: 25/24.

Remember this: SohCahToa
Soh- Sine=opposite/hypotenuse
Cah- Cosine=adjacent/hypotenuse
Toa- Tangent=opposite/adjacent
Hope that helps!

The answer to your question is 24/25. Remember that Cos is taking the adjacent side and the hypotenuse of the triangle from the angle you want calculated.

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. The roots of an equ
Inessa [10]

Answer:

If the roots of an equation are x = -1 ± i, it means that the factorized form of that equation is: (x + 1 + i)(x+ 1 - i) = 0.

Using the distributive property, we have:

(x + 1 + i)(x+ 1 - i) = x^2 + x - ix + x + 1 - i + ix + i + 1

Combining like-terms and simplifying:

⇒ x^2 + x + x + 1   + 1 = x^2 + 2x + 2 = 0

Therefore, the stament is correct. If the roots of an equation are x = -1 ± i, then the equation is: x^2 + 2x + 2 = 0.

Which of the following steps indicates the addition property of equality while solving the equation –1 – 6x = x – 15? Question 4
den301095 [7]

Answer:

B) -1-6 x +15 = x - 15 +15

Step-by-step explanation:

<u>Explanation</u>:-

Given equation is  –1 – 6 x = x – 15

<em>By addition property of equality </em>

<em>                        ⇒     - 1 - 6 x + 15 = x - 15 +15</em>

                      ⇒      - 6 x + 14  = x

subtracting 'x' on both sides ,we get

                       ⇒      - 6 x -x +14 =0

                        ⇒      - 7 x +14 =0

                         ⇒      -7 x = - 14

   Dividing '-7'  on both sides , we get

                                 x  = 2

<em>The solution of given equation is    x  = 2</em>
