You are given that 1 inch = 2.54 centimeters, so to convert 12.4 inches to centimeters, you would multiply 12.4 in by 2.54 cm.
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°
Answer:
6/5 or 1 1/5
Step-by-step explanation:
2/5 + 2/5 + 2/5 = 6/5 or 1 1/5
This is the same as multiplying 3 x 2/5 = 6/5 or 1 1/5
Answer:
y - 7 = -8(x - 1)
Step-by-step explanation:
We are provided with some information
We are given point (1,7)
Slope = -8
Using a point slope form formula
y - y_1 = m (x - x_1)
m = -8
y_1 = 7
x_1 = 1
Inserting the given values into the equation
y - y_1 = m ( x - x_1)
y - 7 = -8 ( x - 1) ( point slope form)
Don't confuse slope intercept form with point slope form
Slope intercept form
y = mx + C
y - point y
m - slope
x - point x
C - intercept
Point slope form
y - y_1 = m(x - x_1)
