Answer:

Step-by-step explanation:

∠DEC + ∠EDC + ∠ECD = 180  {angle sum property of triangle}

45 + 65 + ∠ECD = 180

110 +∠ECD = 180

∠ECD = 180 - 110

∠ECD = 70°

AB // CD and AE transversal

∠BAC = ∠ECD    {Corresponding angles are equal}

∠BAC = 70°

Dada a Matriz A= [1 -2 1 ][-3 1 4] [0 6 8] , escreva uma matriz B diferente de A, tal que detA =detB.
Mariulka [41]

Use o fato de que o determinante de qualquer matriz quadrada é o mesmo da sua transposta.

\mathbf A=\begin{bmatrix}1&-2&1\\-3&1&4\\0&6&8\end{bmatrix}

\mathbf B=\mathbf A^\top=\begin{bmatrix}1&-3&0\\-2&1&6\\1&4&8\end{bmatrix}

T varies inversely with the cube of W. When W is 3, T is 1/9. Find the value of W when T is 1/243
Lera25 [3.4K]
T varies inversely with the cube of W 

T = k/W^3

\frac{1}{9} = k/3^3

k = \dfrac{3^3}{9} = 3

W^3 = k/T

W = \sqrt[3]{ k/T }

When T=1/243

W = \sqrt[3]{ 3/(1/243)}= \sqrt[3]{729} = 9
