the answer would be 33. so the first thing you want to do is turn 7 feet into inches. if 12 inches is equal to 1 foot then 7 feet are equal to 84 inches. then add another 84 inches which will equal 168. the you would want to divide 168/15 which gives you 33.6. this mean that 33 (separate numbers) 15 inches of board from two boards.
hope I was able to help and that my explanation made sense. : )
Answer:
See below ↓↓
Step-by-step explanation:
<u>Finding x</u>
- Both the angles containing the x variable are on the same side of the transversal
- There is a property which states that : two angles on the same side of the transversal are supplementary
- Therefore, they add up to 180°
- ⇒ 8x + 12 + 2x + 18 = 180
- ⇒ 10x + 30 = 180
- ⇒ 10x = 150
- ⇒ <u>x = 15</u>
<u></u>
<u>Finding y</u>
- The angles at the top are vertically opposite angles (VOA), meaning that they are equal
- ⇒ 8x + 12 = 3y - 18
- ⇒ 3y = 8(15) + 12 + 18
- ⇒ 3y = 120 + 30
- ⇒ 3y = 150
- <u>⇒ y = 50</u>
