Arc WTS is twice the measurement of angle R.

So arc WTS equals 2R

Arc WRS is twice the measurement of Angle T.

So arc WRS equals 2T

The sum of the two arcs WTS and WRS equal 360 degrees,


So now we have 2R + 2T = 360.

Divide all terms by 2:

R + T = 180


The sum of supplementary angles equal 180 degrees, therefore angles T and R are supplementary.

Compute 1 + 2 + 3 +....+ 1,997 + 1,998 + 1,999
sp2606 [1]

Answer:

1 999 000

Step-by-step explanation:

Formula:

1+2+3+.\ .\ .+n=\frac{n\times \left( n+1\right)  }{2}

………………………………………

Then

1+2+3+....+1997+1998+1999=\frac{1999\times \left( 1999+1\right)  }{2}

1+2+3+....+1997+1998+1999=\frac{1999\times \left( 2000\right)  }{2}

1+2+3+....+1997+1998+1999=\frac{3998000  }{2}

1+2+3+....+1997+1998+1999=1999000

In an equilateral triangle, the measure of each angle is 60 degrees. Then the value of x and y is 17/3 and 65.

<h3>What is the triangle?</h3>

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In trianlge ΔMNP, PM = 3x - 4, MN = 14, ∠N = 5y - 5.

In an equilateral triangle, all the sides and all the angles are equal.

MN = NP = PM

∠M = ∠N = ∠P

Then we have

   PM = MN

3x - 4 = 14

      x = 17/3

We know in an equilateral triangle, the measure of each angle is 60 degrees. Then we have

    ∠N = 60

5y - 5 = 60

    5y = 65

      y = 13

This is (compound) probability: Picking two numbers from 1-10 and getting a multiple of 3 both times.
NemiM [27]

Answer:

There are 10 counters in the bag and you want the 4

As their is only one for the probability is

1/10

There are now 9 counters left in the bag.

You only want the even ones , which are 2 6 8 and 10 ( four has been taken out)

There are only four even counters in the bag of nine counters so the probability is

4/9

As you want both of these to occur, you need to multiply them

1/10 x 4/9 = 49/90
