Solve the right triangle Round your answer to the nearest tenth

Mathematics
1 answer:
Darina [25.2K]3 years ago
7 0

Answer:

B = 40°

a = 23.0

b = 19.3

Step-by-step explanation:

✔️B = 180° - (90° + 50°) => sum of triangle

B = 40°

✔️Reference angle = 50°

Opp = a

Hypotenuse = 30

Adjacent = b

Find a by applying the trigonometric function, SOH:

Sin 50 = Opp/Hyp

Sin 50 = a/30

30 × Sin 50 = a

23.0 = a

a = 23.0 (nearest tenth)

To find b, apply CAH:

Cos 50 = Adj/Hyp

Cos 50 = b/30

30 × Cos 50 = b

b = 19.3 (nearest tenth)

Suppose the solutions of a homogeneous system of four linear equations in five unknowns are all multiples of one nonzero solutio
Akimi4 [234]

Consider a homogeneous machine of four linear equations in five unknowns are all multiples of 1 non-0 solution. Objective is to give an explanation for the gadget have an answer for each viable preference of constants on the proper facets of the equations.

Yes, it's miles true.

Consider the machine as Ax = 0. in which A is 4x5 matrix.

From given dim Nul A=1. Since, the rank theorem states that

The dimensions of the column space and the row space of a mxn matrix A are equal. This not unusual size, the rank of matrix A, additionally equals the number of pivot positions in A and satisfies the equation

rank A+ dim NulA = n

dim NulA =n- rank A

Rank A = 5 - dim Nul A

Rank A = 4

Thus, the measurement of dim Col A = rank A = five

And since Col A is a subspace of R^4, Col A = R^4.

So, every vector b in R^4 also in Col A, and Ax = b, has an answer for all b. Hence, the structures have an answer for every viable preference of constants on the right aspects of the equations.

An invoice for $450 has terms 2/10, 1/30, n/60. If you pay on the eighth day, how much will you remit? A. $446.00 B. $450.00 C.
elena-s [515]
I believe the answer is: <span> C. $441.00
</span>
the <span>terms 2/10, 1/30, n/60. indicates that you would get 2% discount if you pay within 10 days and 1% discount if you pay within 30 days.

If you pay on the 8th day, the amount of your payment would be:

$ 450 x 98%   = $ 441</span>
