Angles in a Triangle

There are two basic relations of angles we need to recall:

Supplementary angles add up to 180°
Internal angles of a triangle add up to 180°

Note a, b, and c are the internal angles of the triangle. The angle c is what is needed to a+b to complete 180°, thus:

c = 180 - ( a + b )

Also, note c and d are supplementary angles. Again, c is what is needed to d to complete 180°, thus

c = 180 - d

From the two relations above, it follows that:

a + b = d

Lowest common multiple of 12,18,56

Ira Lisetskai [31]

Step-by-step explanation:

12 = 2 × 2 × 3

18 = 2 × 3 × 3

56 = 2 ×2 × 2 × 7

Now

Common factor = 2

Remaining factor = 2 × 3 × 2 × 3 × 7

LCM = RF × CF

= 504

hence the lCM of 12 , 18 and 56 is 504...

A fair spinner has 9 equal sections: 2 red, 3 blue and 4 green.

Alex17521 [72]

Answer:

The Probability of not getting two consecutive reds is 0.9506

Step-by-step explanation:

Number of sections = 9

Number of red sections = 2

Number of blue sections = 3

Number of green sections = 4

Probability of getting two consecutive reds = $\frac{2}{9} \times \frac{2}{9}=\frac{4}{81}$

So,The Probability of not getting two consecutive reds = $1- \frac{4}{81}=\frac{77}{81}=0.9506$

Hence The Probability of not getting two consecutive reds is 0.9506
