I need help with this question. There are 3 circumferences of radius 115, 150, 225. They are externall tangents between them. Which are the angles that are formed when the centers of the circumference come together.
simply the expression by first substituting values from the table of exact values and then simplifying the resulting expression. (tan 45* + tan 60*)^2 (^2=squared)
