1/2. half of the cards(26 out of 52) are red. you can reduce 26/52 to 1/2.

We know that the deck of cards contain half red and half black cards or you can say we have 26 red cards and 26 black cards.
we have to find probability of red cards from a deck of cards
so,
probability (selecting red card) = \frac{26}{52}
                                                     = \frac{1}{2}

Probability ( selecting red card ) =  <span>\frac{1}{2} Answer</span>

In ABC, if CB AC≅ , m∠A = 3x + 18, m∠B = 7x – 58, and m∠C = 2x – 8, find x and the measure of each angle.
lesya692 [45]

Answer:

  x = 19

  A = 30°

  B = C = 75°

Step-by-step explanation:

In an isosceles triangle, the angles opposite the congruent sides have the same measures.

  A = B

  3x +18 = 7x -58

  76 = 4x . . . . . . . . add 58-4x

  19 = x . . . . . . . . . divide by 4

Then the equal angles measure ...

  A = B = 3(19) +18 = 75

  C = 2(19) -8 = 30

Angles A, B, C measure 75°, 75°, 30°, respectively.

_____

<em>Alternate solution</em>

The sum of angles in a triangle is 180°, so you could write ...

  (3x +18) +(7x -58) +(2x -8) = 180

  12x = 228 . . . . . add 48

  x = 19 . . . . . divide by 12

What is the sum of all measures of the interior angles of a regular pentagon?
Ugo [173]
There are 540 degrees total in the interior angles of a regular pentagon.

Just so you know, the total degrees of interior angles goes up by 180 degrees.

A triangle is 180 degrees, a quadrilateral 360, and a pentagon 540.
