Answer:
measure of larger angle = 240 degrees
measure of each of the smaller angles = 120 degrees
Explanation:
In any polygon, the sum of measures of interior angles can be calculated using the following rule:
sum of interior angles = (n-2)*180 where n is the number of sides
Now, for an octagon, n=8, this means that:
sum of measures of interior angles = (8-2)*180 = 1080°
An octagon has 8 interior angles, one of which is twice the measure of the others.
Assume that each of the 7 smaller angles is x degrees and that the larger angle is 2x degrees
Computing their summation, we will find that:
x + x + x + x + x + x + x + 2x = 1080
9x = 1080
x = 120
This means that:
each one of the smaller angles = x = 120 degrees
the larger angle = 2x = 2 * 120 = 240 degrees
Hope this helps :)
Answer:
The slope of line A is C. 2
Step-by-step explanation:
You can check the slope by dividing the rise (how many units up) and the run (how many units across). This line has a rise of rise of 4 and a run of 2. Diving 4 by 2 gives you a slope of 2.
Answer:
Answer is d - x = 
Step-by-step explanation:
Step 1: Add 'z' to both sides
4x -z (+z) = y + z
4x = y + z
Step 2: To solve for x, divide both sides by 4
=
x =
40x - 24 - 33x - 77 = 102
40x - 33x = 102 + 24 + 77
7x = 203
x = 29
Answer:
25 * 10^6
But 10^6 is the same as multiply 10 six times, that is, 10 * 10 * 10 * 10 * 10 * 10 * 10. The result is as simple as writing 1 and six zeros, that is, counting the number of zeros I can see. So, 10^6 = 1000000.
Now, 25 * 10^6 = 25 * 1000000
The final answer is 25000000
