aksik [14]

Answer:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

126° is an exterior angle of the triangle, then

x + 2x + 6 = 126

3x + 6 = 126 ( subtract 6 from both sides )

3x = 120 ( divide both sides by 3 )

x = 40

bogdanovich [222]

Answer:

Step-by-step explanation:

It is given that, in Russia there are 21 rocket launch failures out of 743 total launches. We need to find no of failures for the next 800 launches.

21 rocket = 743 launches

1 launch = $\dfrac{21}{743}\ \text{failures}$

For 800 launches,

$=\dfrac{21}{743}\ \text{failures}\times 800\\\\=22.611\ \text{failures}$

= 23 failures

So, there are 23 failures in next 800 launches.
