Su and vt are chords that intersect at point r.
what is the length of line segment vt?
4 units
8 units
13 units
14 units

we know that

the intersecting chords theorem states that when two chords intersect each other inside a circle, the products of their segments are equal.

so

in this problem

substitutes the values

the length of segment vt is equal to

substitute the value of x

therefore

the answer is

13 units just took test got 100%

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
