1. In a triangle the ratio of two

Mathematics
1 answer:
Stella [2.4K]3 years ago
6 0

<em>Answer:</em>

<em>The unknown angles are 45 and 63</em>

<em>Step-by-step explanation:</em>

<em>5x + 7x + 72 = 180 (angle sum property)</em>

<em>12x + 72 = 180</em>

<em>12x = 180 - 72</em>

<em>12x = 108</em>

<em>x = 108/12</em>

<em>x = 9 </em>

<em />

<em>Therefore, 5x = 5*9 = 45</em>

<em>                 7x = 7*9 = 63</em>

Help please <br>3x-10=56<br>79-y=2x<br>work out x and y​
Lana71 [14]

Answer:

3x-10=56

3x=56+10

3x=66

3x/3 = 66/3

x=11

79-y=2x

79-y=2(11)

79-y=22

79-22=y

y=57

therefore x=11 and y=57

If you are dealt 6 cards from a shuffled deck of 52​ cards, find the probability of getting four queens and two kings.
kicyunya [14]

Answer:

The probability is 0.000000207176

Step-by-step explanation:

In this question, we are asked to calculate the probability that if 6 cards are selected from a deck of cards, we will be having 4 kings and 2 queens.

Before we answer, we should understand that in a deck of cards, there are 4 queens and 4 kings. The probability of selecting a king is the same as the probability of selecting a queen which is 4/52 = 1/13

Okay now we want to find the probability of the six cards being 4 kings and 2 queens. Since the probabilities are equal, we proceed to calculate at the same time.

That would be (1/13)^6 = 0.000000207176

The probability of selecting 4 kings and 2 queens is 0.000000207176
