Answer:

180˚ or C

Step-by-step explanation:

Complementary angles are two angles that add up to 90˚.

Since m∠A = 40˚ then we can write and equation where ∠B equals x.

40 + x = 90

40 - 40 + x = 90 - 40

x= 50

m∠B = 50˚

Supplementary angles are two angles that add up to 180˚.

Since ∠B is the supplement of ∠C, we will use x as the value of ∠C.

50 + x = 180

50 - 50 + x= 180 - 50

x= 130

So ∠C = 180˚

Thus, 50˚ + 130˚ = 180˚

Answer:

Step-by-step explanation:

b and a=40⁰ so if b+c is supplementary they equal 180⁰ together so 180-40= 150⁰

Ticket costs £63 plus a booking fee of 3%. What is the total price of the ticket ?

Arte-miy333 [17]

The answer is £64.89.

Step by Step:

Take the original price multiplied by 0.03 ( the percent of a booking fee ) and add those amounts together.

Equation: 63 + 1.89 = 64.89

Determine whether the set of vectors is a basis for ℛ3. Given the set of vectors , decide which of the following statements is t

schepotkina [342]

Answer:

(A) Set A is linearly independent and spans $R^3$ . Set is a basis for $R^3$ .

Step-by-Step Explanation

Definition (Linear Independence)

A set of vectors is said to be linearly independent if at least one of the vectors can be written as a linear combination of the others. The identity matrix is linearly independent.

Definition (Span of a Set of Vectors)

The Span of a set of vectors is the set of all linear combinations of the vectors.

Definition (A Basis of a Subspace).

A subset B of a vector space V is called a basis if: (1)B is linearly independent, and; (2) B is a spanning set of V.

Given the set of vectors $A= \left(\begin{array}{[c][c][c][c]}1 & 0 & 0 & 0\\ 0 & 1 & 0 & 1\\ 0 & 0 & 1 & 1\end{array} \right)$ , we are to decide which of the given statements is true:

In Matrix $A= \left(\begin{array}{[c][c][c][c]}(1) & 0 & 0 & 0\\ 0 & (1) & 0 & 1\\ 0 & 0 & (1) & 1\end{array} \right)$ , the circled numbers are the pivots. There are 3 pivots in this case. By the theorem that The Row Rank=Column Rank of a Matrix, the column rank of A is 3. Thus there are 3 linearly independent columns of A and one linearly dependent column. $R^3$ has a dimension of 3, thus any 3 linearly independent vectors will span it. We conclude thus that the columns of A spans $R^3$ .
