Find the measure of an angle B of a triangle with the following datas: C=80, side b=40 cm, side c=56cm

Iam trying to solve a linear equation for the shoe size of someone 84" tall taking into consideration example 1 is 69" tall with a shoe size of 9 and example 2 is 72 inches tall with a shoe size of 11. i understand that the equation should be y=mx+b and that on the graph the answer is (3,2) but i just don't understand how to create the equation to solve for 84-inches and 60-inches tall questions. after two days, i need .

What expression is equivalent to log3(x+4)

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5
