Investigate what happens with the “ninth” fractions. E. g. what do you get for 1/9, 2/9, 3/9 etc.

Have you spotted a pattern?

What would 9/9 be as a decimal?

Given:

Fractions etc.

To find:

What happens with the “ninth” fractions.

Solution:

We have, the values of are

Clearly we can spot a pattern, because after decimal the numerator digit of fraction is repeating.

Similarly,

Therefore, the decimal value of is 0.99999..., which is approximately 1.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
