Find the matrix aa of the linear transformation t(m)=[2041]m[2041]−1t(m)=[2401]m[24 01]−1 from u2×2u2×2 to u2×2u2×2, with respect to the standard basis for u2×2u2×2: {[1000],[0010],[0001]}{[1000],[0100 ],[0001]}.

right

step-by-step explanation:

answer: sensy

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
