Itell you these facts about a mystery number, c:
1.5 < c < 2
c can be written as a fraction with one digit for the numerator and one digit for the denominator.
both c and 1/c can be written as finite (non-repeating) decimals.
what is this mystery number? (what is c? )
s much

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
