Find the difference between the midpoint and the known endpoint by subtracting the X and Y values from each other:
X: 10 - 6 = 4
Y: 7 - 4 = 3
Now add those values to the midpoint to find the other endpoint:
X: 10 +4 = 14
Y: 7 +3 = 10
Endpoint = (14,10)
Total ratio is 1 + 3 + 5 = 9
Share for 1 = 1/9 × 144
= 16kg
Share for 3= 3/9 × 144
= 48kg
Share for 5= 5/9 × 144
= 80kg
Proof= 80 + 48 + 16 =144
Answer:
2 1/4
Step-by-step explanation:
-5 1/4- (-7 1/2)
to minus cancel each other out so it becomes a plus
-5 1/4 + 7 1/2
common dinomanater
-5 1/4 + 7 2/4
2 1/4
Hello there! A trapezoid is a quadrilateral, and the angles of a quadrilateral have a sum of 360°. We don't know the angle measurement for A, so let's start off by adding the measurements of the other angles together. 117 + 155 + 25 is 297. Now, we subtract that number from 360 to find the angle measurement. 360 - 297 is 63. There. The measurement of angle A is 63°.
