SAT Question 64c1f044: Right Triangles And Trigonometry answer and explanation with Desmos solution

Choice C is correct. The tangent of an acute angle in a right triangle is defined as the ratio of the length of the side opposite the angle to the length of the shorter side adjacent to the angle. In the triangle shown, the length of the side opposite the angle with measure $x^{\circ }$ is $26$ units and the length of the side adjacent to the angle with measure $x^{\circ }$ is $7$ units. Therefore, the value of $\tan x^{\circ }$ is $\frac{26}{7}$.
