When simplifying rational numbers, what would the answer be to 57/69
Irina-Kira [14]
You don't simplify rational numbers, but sometimes you can simplify a fraction.
The way to do that is to divide the top and bottom by their greatest common factor.

The greatest common factor of 57 and 69 is 3 .  When you divide the top and
bottom by 3 , you have  19/23 .  That's the simplest form of that particular fraction.

If &lt;a is 89.5, what is the measure of its complementary angle?​
Pachacha [2.7K]

Answer:

The complement of an angle is what, when added to it, equals 90 degrees (90°). For example, in your problem, 90°-85°=5°. This means that the complement of 85° is 5°, since they add up to equal 90 degrees a right angle.

The supplement of an angle is what, when added to it, equals 180 degrees.

For example, in your problem, 180°-85°=95°. This means that the supplement of 85° is 95°, since they add up to equal 180 degrees a straight angle.

Which lines, if any, must be parallel based on the given information? Justify your conclusion.
77julia77 [94]
A must be parallel to b.

Proof:
∠3 = <span>∠13 (given)
</span>∠15 = <span>∠13 (vertically opposite angles are equal)
Since </span>∠13 = ∠3 and ∠13 = ∠15, ∠15 = <span>∠3

Then, a must be parallel to b (transverse line d cuts parallel lines producing converse alternate angles that are equal (ie </span>∠15 = <span>∠3))
