2 would be the base and 3 will be the square
Answer:
2(x + 5) = x - 2
⟹ x = -12
Step-by-step explanation:
Doubling the sum of 5 and a number is equal to the same number decreased by 2. What is the equation?
This word problem can be written as:
⟹ 2(x + 5) = x - 2
1. Distribute:
2(x) + 2(5) = x - 2
⟹ 2x + 10 = x - 2
2. Subtract x from both sides:
2x - x + 10 = x - x - 2
⟹ x + 10 = -2
3. Subtract 10 from both sides:
x + 10 - 10 = -2 - 10
⟹ x = -12
4. Check your work:
2(x + 5) = x - 2
2(-12 + 5) = -12 - 2
2(-7) = -20
⟹ -14 = -14 ✔

Answer:
x = -70
Step-by-step explanation:
x+47=−23
Subtract 47 from both sides.
x+47−47=−23−47
x = −70

The relationship between the trigonometric ratios are cos(X) = cos(A), cos(Y) = cos(C) and cos(Z) = cos(B)
<h3>The relationship between the trigonometric ratios</h3>
The given parameters are:
- Scale factor of dilation, k = 2
- cos(X) = 2.5/5/59
Since the transformation is a dilation, it means that both triangles are similar.
So, we have:
cos(X) = cos(A), cos(Y) = cos(C) and cos(Z) = cos(B)
<h3>The segments AC and AB. </h3>
In (a), we have:
Both triangles are similar.
This means that the corresponding points are:
X and A
Y and C
Z and B
So, we have:
AC = 2 * XY
AB = 2 * XZ
