Not a theorem. But ok.
because of where its located it is equal to the other angle or
x+12=110.
isolate x
x=110=12
x=98

Bisectors of angles A, B and C of a triangle ABC intersect its circumcircle at D, E and F respectively. Prove that the angles of
Simora [160]

Answer:

The region between a chord and either of its arcs is called a segment the circle.

Angles in the same segment of a circle are equal.

Step-by-step explanation:

Let bisectors of angles A, B and C of a triangle ABC intersect its circumcircle at D, E and F . 

Now from figure,

∠D = ∠EDF

∠D = ∠EDA + ∠ADF

Since ∠EDA and ∠EBA are the angles in the same segment of the circle.

So  ∠EDA  = ∠EBA

Hence  ∠D = ∠EBA + ∠FCA

Again  ∠ADF and ∠FCA are the angles in the same segment of the circle. 

hence ∠ADF = ∠FCA

Again since BE is the internal bisector of ∠B and CF is the internal bisector of ∠C

So ∠D = ∠B/2 + ∠C/2

Similarly

∠E = ∠C/2 + ∠A/2

and 

∠F = ∠A/2 + ∠B/2

Now ∠D = ∠B/2 + ∠C/2

=∠D = (180 - ∠A)/2

 (∠A + ∠B + ∠C = 180)

∠D = 90 - ∠A/2

∠E = (180 - ∠B)/2

∠E = 90 - ∠B/2

and ∠F = (180 - ∠C)/2

∠F = 90 - ∠C/2

Two fair dice are thrown one red one black. what is the probability that the red die comes up 1 given that the black die comes u
Iteru [2.4K]
Probability that red is 1 is \frac{1}{6}

Probability that black is 3 is \frac{1}{6}


The probability that both of these events happen at the same time is \frac{1}{6}* \frac{1}{6}

A submarine was situated 800 feet below sea level.
Ghella [55]

Answer:

New position = -525 ft or 525 ft below the sea level

Step-by-step explanation:

Lets h be the height of the sea.

Given:

A submarine was situated 800 feet below sea level.

It is ascends 275 feet.

We know that h = 0 on the surface of the sea.

When we go below the surface vertically inside the sea the height will become negative.

So the submarine was situated h = -800 feet below the sea level, and it is ascends 275 feet from -800 feet.

So the new height of the submarine is.

h = -800 + 275

h = -525\ ft

Therefore the new position of the submarine is 525 below the sea level.
