A slope intercept calculator is a tool used to determine the slope intercept form of a equation for a line passing through two points on a Cartesian coordinates plane
To find the missing two angle measures, you will need to know that the sum of all nine angles in a nonagon equal 1260 degrees.
Knowing this, you can use this total to find the missing congruent angles.
Start with the total and subtract what you know. Divide what is left by two to get each angle measure.
1. 1260 - ( 138 + 154 + 145 + 132 + 128 + 147 + 130) = 286
2. 286/2 = 143
The missing angles are each 143 degrees.
Area of rectangle = 60 x 20 = 1200
area of circle = πr^2 = π * 10^2 = 100<span>π
3 circles = 100</span>π x 3 = 300<span>π
shaded area = 1200 - 300</span>π = 300(4 -<span>π)
</span>
--------------------------------
if you want to apply <span>π = 3.14 then
</span>shaded area = 1200 - 300π = 300(4 -3.14) = 257.52
