What is the value of the missing angle (x+15)

Mathematics
1 answer:
Luden [163]3 years ago
4 0

Answer:

x = 70

Step-by-step explanation:

The total interior angle in a square, even with not a perfect square, adds to 360

Set your formula up as

360 = (x+15) + x + 115 + 90

360 - 115 - 90 - 15 = 2x

140 = 2x

140/2 = x

70 = x

Answer:

672 students

Step-by-step explanation:

To find the answer you would first need to find how many people out of the 75 middle school students didn't prefer apples. Since 67 out of 75 students liked apples we can only assume the other 8 students didn't prefer apples. We will then divide 8 by 75 to get the percentage. This will give us the percentage .106. Next multiply 6,300 by .106 and we get 672.

The perimeter of a rectangular field is 360yd. The length is 20yd longer than the width. Find the dimensions
Tju [1.3M]
If P=360, then 360yd / 4 sides = 90yds each side. Now that it is a rectangle, the Length should be more than the width, so if the length is 20yds more than the width, do 90 - 20 two times,  Width= [ (90yds - 20yds)*2 ] 

To sum things up, Length = 110; Width = 70. | 110*2 = 220, 70 * 2 = 140, 220+140 = 360.
