Step-by-step explanation:
The given matrix equation is:

To find Matrix X, we need to multiply both sides of the equation by 2 to obtain:

This simplifies to;

By scalar multiplication, we multiply each entry in the matrix A by to 2 to obtain matrix X.

The diagrammatic sketch of the details given in the question was attached in the picture below.
From the picture below, the distance between the two kites is represented by (c) and can be calculated by using the cosine angle rule which is illustrated as:

where;
a = 110
b = 104
Cos C = 26°
Then;

I think number #29 is A but may be B and number #30 is C
Answer:
281 ft^2
Step-by-step explanation:
We need to add each individual 2d shape together to find the surface area
Bottom: 5*12 = 60
Left side and right side: 4*5 = 20, 2 sides so 20*2= 40
Side facing us and side facing away from us: 12*4 = 48, 2 sides so 48*2=96
Top side that is cut by base of triangle: 7*5 = 35
Each triangle face: base = 5 (12-7), height = 5 1/2base * height so each triangle is .5*5*5 = 12.5; 4 triangles so 12.5*4=50
60+40+96+35+50=281
