Answer:

it's 20

Step-by-step explanation:

(X+5)° + (7x-5)° + x°= 180° { sum of the three angles of the triangle is 180°}

X+5+7x-5+X = 180

X+7x+X+5-5= 180

9x+0 = 180

9x = 180

therefore X= 180/9

= 20

All angles are of triangle and thus give sum of 180⁰

x + 5 + 7x - 5 + x = 180⁰

9x = 180⁰

x = 20⁰

Answer:

A

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosA = \frac{adjacent}{hypotenuse} = \frac{AC}{AB} = \frac{2}{3} , thus

A = cos^{-1} (\frac{2}{3} ) ≈ 48° → A

Complete question :

Compute the probability of each of the following events.

Event : The sum is greater than 6

Event : The sum is not divisible by 2

Answer:

7/12 ; 1/2

Step-by-step explanation:

Sample space :

2, 3, 4, 5, 6, 7

3, 4, 5, 6, 7, 8

4, 5, 6, 7, 8, 9

5, 6, 7, 8, 9, 10

6, 7, 8, 9, 10, 11

7, 8, 9, 10, 11, 12

Probability that sum is greater than 6:

Number of outcomes greater Than 6 = required outcomes = (7,7,7,7,7,7,8,8,8,8,8,9,9,9,9,10,10,10,11,11,12) = 21

Total sample space = total possible outcomes = 36

Probability = required outcome / Total possible outcomes

P(sum is greater Than 6) = 21 / 36

2.)

Obtaining an even number :

Sum not divisible by 2 = required outcomes = (3, 5, 7, 3, 5, 7, 5, 7, 9, 5, 7, 9, 7, 9, 11, 7, 9, 11) = 18

Total sample space = total possible outcomes = 36

P(sum is not divisible by 2) = 18 / 36 = 1 / 2
