Answer:

Step-by-step explanation:

The triangle sum therom states that the interior angles of a triangle add up to 180 degrees. So all you have to do is make an equation 2x+2x+x=180 and solve from there.

Solve for x. NEED HELP

TiliK225 [7]

Answer:

22.470

Step-by-step explanation:

In this example you have to use the trigonometric function sine which is defined as $sin(\theta) = \frac{opposite}{hypotenuse}$

Plug in known values:

$sin(64) = \frac{x}{25}$

Multiply both sides by 25

$sin(64) * 25 = x$

Approximate sin(64) using a calculator:

$0.89879 * 25 = x$

Simplify

$22.470 \approx x$

you have $120 to donate equally to several charities. Does this situaton represent direct or inverse variation? Explain.

SOVA2 [1]

This situation represents inverse variation.

The difference between direct and inverse variation is in direct variation, as one variable goes up the other does too, while in inverse, as one variable goes up the other falls.

In this case, as you donate to more charities, the amount you donate to each charity falls, because you donate an equal amount. This means it's inverse variation.

Hope this helps!

In right triangle ΔABC (m∠C = 90°), point P is the intersection of the angle bisectors of the acute angles. The distance from P

arlik [135]

Answer:

28 inches

Step-by-step explanation:

The point of intersection of the angle bisectors is the incenter. It is the center of a circle tangent to the three sides of the triangle. The circle has radius 2.

In the attached figure, we have labeled the points of tangency D, E, and F. We know that CE and CF are both of length 2, and we know that the points of tangency are the same distance from an external point where the tangents intersect. That means DA = FA and DB = EB.

The perimeter of the triangle is ...

P = DA +DB +FA +EB +CF +CE

Using the above relations, this can be written as ...

P = DA +DB +DA +DB +CF +CE = 2(DA +DB) +2(CE)

We are told that AB is 12 inches, so DA +DB = 12 inches. We also know that CE = 2 inches, so the perimeter is ...

P = 2(12 in) + 2(2 in) = 28 in

The perimeter of triangle ABC is 28 inches.
