Answer:
12cos59, about 6.18
Step-by-step explanation:
cos59 = x/12
(adjacent/hypotenuse)
x = 12cos59
plugging this into a calculator gets you about 6.18
Let x = the older student
Let y = the younger student
Let z = the teacher.
x = 2y
z = 5x
z + 5 = 5y Somehow this does not look like its going to be nice.
z = 5y - 5
Since z = 5y - 5 we have
5y - 5 = 5x
y - 1 = x Here's the problem. there is a contradiction. You need to make y bigger, not smaller.
