Answer:

The answer to your question is:  B and D are correct

Step-by-step explanation:

Remember that the sum of the internal angles in a triangle equals 180°.

The sum of supplementary angles equals 180°

Then

                (6x + 1) + (4x + 5) + [180 - (8x + 30)] = 180

                6x + 1 + 4x + 5 + [180 - 8x - 30] = 180

                10x + 6 + 150 - 8x = 180

                2 x = 180 - 156

                2x = 24

                x = 24/2

                x = 12

∠JKL = 4(12) + 5 = 48 + 5 = 53

∠KJL = 6(12) + 1 = 72 + 1 = 73

∠KLJ = 180 - 73 - 53 = 54

∠KLM = 126

Prove that \displaystyle \frac{\cos \theta}{1 + \sin \theta} = \frac{1 - \sin \theta}{\cos \theta}
Bogdan [553]

Answer:

sin^2(θ)+cos^2(θ)=1

Step-by-step explanation:

We know that the statement above is true because of the Pythagorean identity theorem, which states the aforementioned equation. If you solve the equation for 1 you get the same equation.

To do this first multiply both sides by cos(θ), this gives you (cos^2θ)/1+sinθ = 1-sinθ

Then, multiply both sides by sinθ. This equals cos^θ=1-sin^2θ.

Finally, add sin^2θ to both sides. This equals the final answer of cos^2θ+sin^2θ=1. Which is true.

For which mapped relation is the domain {1,2,3}?
Serga [27]

Answer:

C

Step-by-step explanation:

For any given function, all first input values (x-values/coordinates) in the relation are considered as the domain values. While the output values (y-values/coordinates) make up the range of the given function.

The mapped relation that has a domain of {1,2,3}, is the mapped relation that has 1, 2, and 3 on the input side on our left.

Therefore, the mapped relation in option C is the answer.

Solve the system of linear equations by using the substitution method. Write your answer as a coordinate/point. (20 points)
Inessa [10]

Answer:

(1,10)

Step-by-step explanation:

Substitute the value of y so you get -5x+15=-2x+12.  Then solve you get x=1. Substitute x as 1 in the equation y=-2x+12 so you get y=10

What actual floor number do each student live on? Show your work also.
Ugo [173]

Heathe lives halfway up: 42 / 2 = 21st floor.

Raveen = 42 x 4/7 = 168/7 = 24th floor.

Alveera = 42 x 3/14 = 126/14 = 9th floor.

Rafi = 42 x 4/6 = 168/6 = 28th floor.

Suha = 28-24 = 4 /2 = 2 = 24+2 = 26th floor.

Arabi = 42 x 2/3 = 84/3 = 28th floor
