A seamstress is making a decorative pillow and wants to sew lace around the trim. The pillow is in the shape of a triangle with
vertices (7, 7) (10, 3) (7, 3). How many inches of lace will she need if each unit on the grid is one inch?
1 answer:
Use the distance formula in order to find the length of each side of the triangle.
<span>>(7, 7) & (10, 3)
</span>√[(7-10)² + (7-3)²] = 5
<span>
></span><span>(10, 3) & (7, 3)
</span>√[(10-7)² + (3-3)²] = 3
>(7, 7) & (7, 3)
√[(7-7)² + (7-3)²] = 4
Adding all lengths (or solving for perimeter), we have: 5 + 3 + 4 = 12
The seamstress will need 12 inches of lace.

Answer:
B
Step-by-step explanation:
Cross multiplication :)
C = 150000 + 17n
where,
C = Total Cost per year = Fixed Cost + Variable Cost
n = Number of Widgets produced each year
17n = Variable Cost
150000 = Fixed Cost

Step-by-step explanation:
The sum of angles in a quadrilateral is 360°.
75° +125° +∠T +60° = 360°
∠T = 360° -260° = 100°
