Answer:
Part A:
- angle ACB= 60° (ABC equilateral triangle.)
- Angle ECD=EDC= (180°-32°)/2= 148/2= 74° (sum of angles in a triangle is equal to 180, and triangle ECD is isosceles since it's given that CE=DE.
- x= 180°-(60°+74°)
= 180°-134°
= 46°
x= 46°
Part B:
120°
<u>Answer:</u> The slope of the line formed by these two points is
<u>Step-by-step explanation:</u>
To calculate the slope, we use the formula:
For the coordinates given:
Putting values in above equation, we get:
Hence, the slope of the line formed from these two coordinates is
Old price: 1,137.50 / 350 = 3.25
New price (at least): 1,500 / 350 = 4.3 (result is rounded)
