Question

error analysis on a math test the students are given a right triangle. one of the acute angles has measure of the other acute angle? what error might the student have made? the measure of the other acute angle is 38°. what error might the student have made? a. the student only subtracted the right angle from 180°. b. the student subtracted the sum of the two given angles from 360°. c. the student only subtracted the acute angle from 180°. d. the student added the right angle and the given acute angle, but did not subtract the sum

Explanation:

En un triángulo rectángulo, la suma de los ángulos internos es \(180^{\circ}\). Si hay un ángulo recto (\(90^{\circ}\)) y un ángulo agudo dado, para encontrar el otro ángulo agudo se debe restar la suma del ángulo recto y el ángulo agudo dado de \(180^{\circ}\). Si un estudiante solo resta el ángulo recto de \(180^{\circ}\), no está teniendo en cuenta el ángulo agudo dado.

Answer:

A. The student only subtracted the right angle from \(180^{\circ}\)
