All you have to do to find this answer is add 102 and 31. which you would than get 133. After that you would take 180 and subtract 133. Than you would get 47.

47 is your answer!!
Hope i helped ^-^

Answer:

Measure of angle x is 47°.

Step-by-step explanation:

We are given a triangle with measure of two angles given as 102° and 31°.

We have to find the value of third angle .

Angle sum property of a triangle states that the sum of angles of a triangle is always 180°

Lets name the triangle first as ΔABC,

Applying angle sum property

∠A + ∠B + ∠C = 180°

Substitute the values, we get,

x°+ 102° + 31° = 180°

x°+ 133° = 180°

x°= 180° - 133°

x° = 47°

Thus, measure of angle x is 47°.

I'll solve 21, and you then should be able to solve the rest on your own!

Since ADC is 135, that means that that whole angle is 135 degrees. In addition, since angles ADB and BDC add up to ADC, we get ADB+BDC=ADC=135=11x+9+7x=18x+9. Subtracting 9 from both sides, we get 126=18x. Dividing both sides by 18, we get x=7. Plugging that into 11x+9=BDC, we get 11*7+9=77+9=86

Answers:

P(A) = 7/12

P(B) = 1/2

=====================================================

Explanation:

To see how I calculated P(A), check out this link to this very similar question

brainly.com/question/27669586

--------------------

Now to calculate P(B)

If a number is divisible by 2, then the number is a multiple of 2.

In other words, the number is even.

Counting through the values in the table, you should find that there are 18 sums that are even (2, 4, 6, 8, 10 and 12). Refer to the dice chart below.

Here's a further breakdown

  • 1 copy of "2"
  • 3 copies of "4"
  • 5 copies of "6"
  • 5 copies of "8"
  • 3 copies of "10"
  • 1 copy of 12

Side note: We have nice symmetry going on.

There are 1+3+5+5+3+1 = 18 values total that are even numbers. The other half are odd numbers of course.

P(B) = 18/36 = (1*18)/(2*18) = 1/2
