Answer:
Right
Step-by-step explanation:
A right triangle has acute angles and is an equilateral triangle.
Answer:
150°
Step-by-step explanation:
The two angles form a straight line (the arrows on the ends of the lines tells you that it's a straight line), so they form 180° when added together.
The ratio 1 : 5 tells us that there are 6 total parts made up by the angles. Find the value of one part, then you can find the value of <ZXY
To do this, divide 180° by 6 to find out what one part equals.
180°/6 = 30°
So one part is 30°
<WXZ is 30° since it makes up one part
<ZXY is 150° since it makes up 5 parts { (30°)(5) = 150° }
Answer:
The total the salesperson makes is $64.80.
Explanation:
Since nine percent of $720 is $64.80, that is what the salesperson gets per week if they sell $720 worth of jewelry per week. The amount the store gets is $655.20. Thank you for reading, and please mark Brainliest if you got it right!
Answer:
Step-by-step explanation:
![{x}^{4} - 16 \\ = ({x}^{2})^{2} - ({2}^{2})^{2} \\ = ( {x}^{2} - {2}^{2} )( {x}^{2} + {2}^{2} ) \\ = (x - 2)(x + 2)( {x}^{2} + 4)](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B4%7D%20%20-%2016%20%5C%5C%20%20%3D%20%20%28%7Bx%7D%5E%7B2%7D%29%5E%7B2%7D%20%20%20-%20%20%28%7B2%7D%5E%7B2%7D%29%5E%7B2%7D%20%20%20%5C%5C%20%20%3D%20%28%20%7Bx%7D%5E%7B2%7D%20%20-%20%20%7B2%7D%5E%7B2%7D%20%29%28%20%7Bx%7D%5E%7B2%7D%20%20%2B%20%20%7B2%7D%5E%7B2%7D%20%29%20%5C%5C%20%20%3D%20%28x%20-%202%29%28x%20%2B%202%29%28%20%7Bx%7D%5E%7B2%7D%20%20%2B%204%29)
