The measures of the angles of a triangle are represented by n°, n°, and
4n°. Find the measure n:

In a right triangle, the measure of an acute angle is 4 times the
measure of the other angle which is n°. Find the measure n:

Respuesta :

n=30°. The sum of the angles is 180º. n+n+4n=6n, so 6n=180 and n=30°.
n=18°. 4n+n=90, so 5n=90, n=18°.
