Ascalene 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.1.  122 = 112 + 62 − 2(11)(6)cos(y)2. 144 = 121 + 36 − (132)cos(y)3. 144 = 157 − (132)cos(y)4. −13 = −(132)cos(y) degrees

James wants to promote his band on the internet. site a offers website hosting for $4.95 per month with a $49.95 startup fee. site b offers website hosting for $9.95 per month with no startup fee. for how many months would james need to keep the website for site a to be a better choice than site b? define a variable for the situation. write an inequality that represents the situation. solve the inequality to find out how many months he needs to keep the website for site a to be less expensive than site b. using words, describe how many months he needs to keep the website for site a to be less expensive than site b.
