Answer:
k = 45
The angles are 45 , 45, 90
Step-by-step explanation:
The sum of the angles of a triangle are 180
45+ k+2k = 180
Combine like terms
45+3k = 180
Subtract 45 from each side
45+3k-45 = 180-45
3k = 135
Divide by 3
3k/3 = 135/3
k =45
The angles are 45, k,2k
The angles are 45 , 45, 90
Answer:
$10.80
Step-by-step explanation:
Given:
Total number of CDs = 6
Cost price (including tax) = $71.40
Each CD had a tax of $1.10
To find the price of each CD before tax Let's first find the price of each CD after tax.
Price after tax = ![\frac{71.40}{6} = 11.90](https://tex.z-dn.net/?f=%20%5Cfrac%7B71.40%7D%7B6%7D%20%3D%2011.90)
Price of each CD after tax = $11.90
Since each CD had a tax of $1.10, price of each CD before tax would be : $11.90 - $1.10 = $10.80
Therefore price of each CD before tax is $10.80
Answer:
11.18 or 11 yards
Step-by-step explanation:
15² - 10² = x²
225 - 100 = x
225 - 100 = 125
√125 = 11.180339887498948482045868343656
11.180339887498948482045868343656 rounded to the nearest hundredth is 11.18; to the nearest tenth is 11.2; and to the nearest one is 11.
