Consider a linear system with 5891 equations and 3789 variables. Let A be the augmented matrix for this system. Required:
Let FA be the linear transformation whose standard matrix is A. Write down the domain and codomain of FA.

my answer is$ 12

step-by-step explanation:

because 15 -2=12

pi x^2

step-by-step explanation:

pi times x squared

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
