Question

A right triangle has one angle that measures 13.7°. what is the measure of the other acute angle

Answer 1

one of the angles of a right triangle is always 90 degrees. we have another 13.7 degrees angle. so we can find the other acute angle
$180 - (13.7 + 90) = 180 - 103.7 \\ = 76.3$
the other acute angle measures 76.3
