A scalene triangle has the lengths 6, 11, and 12. Keyla uses the law of cosines to find the measure of the largest angle. Complete her work and find the measure of angle Y to the nearest degree.

The maximum angle is 84.3 degree.

Step-by-step explanation:

Sides of a triangle is

a = 6 , b = 11, c = 12

The maximum angle is opposite to c.

So,

Step-by-step explanation:

The general formula for exponential decay given a half-life is

where N(t) is the amount at time t, is the initial amount (at time t=0), and is the half life of the substance.

The half life of carbon-14, is approximately 5,730 years.

= 5730 years

= 6 milligrams

Therefore:

Amount of carbon-14 remaining in the bone fragment after t years is:
