Given:
Measure of the internal angles of the regular polygon
To find:
The missing measure of angle x.
Solution:
The clear image of the question is attached below.
Number of sides (n) = 8
<u>Sum of interior angles of a regular polygon:</u>
Sum = (n - 2) × 180°
Substitute n = 8.
105° + 110° + 150° + 125° + 110° + 159° + 160° + x = (8 - 2) × 180°
919° + x = 6 × 180°
919° + x = 1080°
Subtract 919° from both sides.
919° + x - 919° = 1080° - 919°
x = 161°
The measure of the internal angle x is 161°.
Answer:
okay but it is a LOOP loop Left to a more important point is that the answer to this area is to be randomly in the project

Answer:
1.125,−1.125
Step-by-step explanation:
64x^2+10=91
64x^2+10−10=91−10
64x^2=81
64x^2
/64 = 81

x=1.125,−1.125
Answer:
Step-by-step explanation:
Use the following equation the find the slope:
Rise over run is the change in the y-axis over the change in the x-axis from one point to the other. This is also known as the "slope". Insert the known values:
Solve:
Simplify. Two negatives make a positive:
Simplify fraction by dividing top and bottom by 5:
The slope is 3.
:Done
Alright this equation has two big steps. First we need to find the price after it was marked up, then we need to take that number and find the discounted price.
To find the cost after a percent of it was added, we just need to multiply the two together and add.

23.50

(we divide by 100 to get the number out of a percent)

Ok now that we have the number after the price increase, we now need to find the final answer after a discount of

(do the exact same idea as above but switch the sign)
