Answer:

hope it helps

Step-by-step explanation:

4x-3=2x+25

step1: you collect like terms by crossing over values that are of the same kind and their signs also change as they cross the equal to sign

4x-2x=25+3

2x=28

step2: in order to find the value of x, you need to make it the subject of formula, which can be done by dividing the coefficient of x by itself on both sides

2x/2=28/2

x= 14

Someone please help me state all the possible names for the figure
Otrada [13]

Answer:

B.

Step-by-step explanation:

To answer, lets look at the definitions of each name.

First, a quadrilateral. A quadrilateral is a polygon in Euclidean plane geometry with four edges and four vertices, so it basically just has 4 sides, which this figure has, so this figure is a quadrilateral.

Next, a parallelogram. A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel. So as long as a figure has 4 sides and at least 2 opposite sides that will never collide, it is a parallelogram. Because our figure has 4 sides and each pair of opposite sides is parallel, this figure is a parallelogram.

Last, a rectangle. A rectangle is a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square. So, as long as there are 4 sides and 4 right angles, and 2 of the opposite sides are longer than the other set of opposite sides, it is a rectangle, and this figure fills all the requirements.

So, since the figure is a quadrilateral, a parallelogram, and a rectangle, the answer is B.

Hope this helps :)

Find sin0, cos0, tan0
djverab [1.8K]

Answer:

sin(θ) = 12/13, cos(θ) = 5/13, tan(θ) = 12/5

Step-by-step explanation:

We need to find sine, cosine, and tangent of theta for this triangle.

First, define the different trigonometric functions:

- sine is opposite side to the angle divided by the hypotenuse (longest side not adjacent to the 90 degree angle)

- cosine is the adjacent side next to the angle divided by the hypotenuse

- tangent is the opposite side to the angle divided by the adjacent side

Now, look at theta (θ):

- the opposite side is marked 12

- the adjacent side is marked 5

- the hypotenuse is marked 13

So:

- sin(θ) = opposite / hypotenuse = 12/13

- cos(θ) = adjacent / hypotenuse = 5/13

- tan(θ) = opposite / adjacent = 12/5

Thus the answers are: sin(θ) = 12/13, cos(θ) = 5/13, tan(θ) = 12/5.
