1. In an isosceles triangle, two sides and the angles opposite them are equal.
2. The sum of angles in any triangle is 180^\circ
3. Let the measure of the equal angles be x
4. The equation is 2x + 30 = 180
5. Solve for x
2x = 150 \\
x = \frac{150}{2} = 75
6. The measurement of the equal angles is 75^\circ

Math question: What is the period and range of the tangent function f(x) = tan x?Answer: The period of the tangent function is π (or 180°) because it repeats every π units. The range of f(x) is (-∞, +∞) as it extends infinitely both in the positive and negative directions. However, the function has vertical asymptotes at x = (n + 1/2)π, where n is an integer, meaning it never reaches those values.
