Answer:
x = 14
Step-by-step explanation:
This problem requires and understanding about interior sum of angles.
This is an irregular hexagon. so Total angle sum = 180*(6 - 2) = 720 degrees.
...
80 + 56 + 61 + 43 + 92 + 2x = 360
332 + 2x = 360
2x = 360 - 332
2x = 28
x = 14
or... 6*180 - (332 + 2x) = 720
748 - 2x = 720... x= 14
Answer:
A) 2a + 6
Step-by-step explanation:
(5a + 3) + (2a + 3) + x = 9a + 12
Add both side lengths plus the unknown side to equal the perimeter.
7a + 6 + x = 9a + 12
-7a -6 -7a -6 Subtract 7a + 6 on both sides
x = 2a + 6 This is the missing side length.
Answer:
Step-by-step explanation:
Standard equation of an ellipse,
(h, k) is the center of the ellipse
Value of a = Distance of the center from the vertex
b = Distance of the center from the covertex
From the picture attached,
a = Distance of the center (h, k) from the vertex (2, -2) = 3 units
b = Distance of the center (h, k) from the co-vertex (-1, 0) = 1 unit
Center of the ellipse (h, k) = (-1, -2)
