Answer:
Step-by-step explanation:
The formula for finding the sum of the measure of the interior angles in a regular polygon is expressed as (n - 2) × 180.
Where
n represents the number of sides of the polygon.
5a) The polygon has 11 sides. Therefore, sum of angles is
(11 - 2) × 180 = 1620
The measure of each angle is
1620/11 = 148.3°
b) n = 24
Therefore, sum of angles is
(24 - 2) × 180 = 3960
The measure of each angle is
3960/24 = 165°
5a) n = 7
Therefore, sum of angles is
(7 - 2) × 180 = 900
The measure of each angle is
900/7 = 128.6°
5b) n = 10
Therefore, sum of angles is
(10 - 2) × 180 = 1440
The measure of each angle is
1440/10 = 144°
Answer:
100°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
∠ACB = 180° - (90 + 50)° = 180° - 140° = 40°
∠ECD = 40° ( vertical angle to ∠ACB )
Since CE ≅ ED then ΔCDE is isosceles and
∠CDE = ∠ECD = 40°
∠E = 180° - (40 + 40)° = 180° - 80° = 100°

Step-by-step explanation:
- Critical Path Analysis is presented using the circle and arrow diagrams.
- Earliest Start Time = the earliest possible time of starting the activity
- An arrow running between two event circles shows the activity needed to complete that task.
- All arrows run left to right
- Time for doing just task E = 8 hours (as shown in the figure)
Answer:
10
Step-by-step explanation:
First, you multiply j and k together. j·k=6·4= 24.
Next, you multiply 24 by 2.5. That is equal to 60.
After that, since j=6, you divide 60 by 6.
That is equal to 10.

x = 5.
I attached an image of my work!
Step 1: Subtract 8 from both sides
4x = 20
Step 2: Divide each side by 4
x = 5
