Considering the angle a by cosine rule
11^2 =7 ^2 +15^2 - 2(7)(15)cos(a)
When you do the maths,
Cos(a) =153/210 =0.729
a= cos inverse of 0.729
a=43 degrees


Considering angle b
7^2=15^2 +11^2 -2(11)(15) cos(b)
This will result in cos(b) =297/330=0.9
b= cos inverse of 0.9 = 25.8 degrees


Considering angle c
15^2=7^2 +11^2 - 2(11)(7) cos(c)
Cos(c) will be = -55/154 = -0.357
c= cos inverse of -0.357=110.9

Comparing the angles a,b and c,
C is the largest size in the triangle with an angle of 110.9 degrees

Am I right please ??

Answer:

The answer is: the second one

Step-by-step explanation:

                                             (2x + 2)/y = 4w + 2

pass y to the right side        2x + 2 = y(4w + 2)

expand                                   2x +2 = 4wy + 2y

pass 2 to the right                2x = 4wy + 2y -2

pass 2 to the right                x = (4wy + 2y - 2)/2

simplify                                  x = 2wy + y - 1 or = 2yw + y -1

What od linear algebra exactly?
Alex73 [517]

Answer:

Linear algebra is the study of lines and planes, vector spaces and mappings that are required for linear transforms. It is a relatively young field of study, having initially been formalized in the 1800s in order to find unknowns in systems of linear equations.
