The measure of < A is 45 degree

VashaNatasha [74]

We are given $\triangle ABC \cong \triangle EFG$

The order of the letter sequence is important. The letters pair up based on how they are arranged. We see that A and E are the first letters of the sequences. So this means that angles A and E are the same measure

angle A = angle E

3x+20 = 5x-80

3x-5x = -80-20

-2x = -100

x = -100/(-2)

x = 50

Use this x value to find the measure of angle A

angle A = 3x+20

angle A = 3(50)+20

angle A = 150+20

angle A = 170 degrees

<h3>Therefore, the statement "the measure of angle A is 45 degrees" is <u>false</u>.</h3>

jarptica [38.1K]

Answer:

True

False

Step-by-step explanation:

TRUE

If the equation Ax = 0 has only the trivial solution, then A is row equivalent to the n × n identity matrix

Here's why

If the equation Ax = 0 has only the trivial solution the determinant of the matrix is NOT 0 and the matrix is invertible therefore it is row equivalent to the nxn identity matrix.

TRUE

If the columns of A span ℝ^n , then the columns are linearly independent

Here's why

Remember that the rank nullity theorem states that

$\text{rank}(A) + \text{Nullity}(A) = \text{Dim}(V)$

According to the information given we know that

$\text{rank}(A) = n \\dim(V) = n \\$

Therefore you have

$n + \text{Nullity}(A) = n$

and

$\text{Nullity}(A) = 0$

Which is equivalent to the problem we just solved.

FALSE

If A is an n × n matrix, then the equation Ax = b has at least one solution for each b in ℝ^n

Here's why

Take b as a non null vector and A=0, then Ax = 0 and Ax=b will have no solution.
