The measurement of one angle of a right triangle is 42°. What is the measurement of the missing angle? °

OpenStudy (ashes.boom):

all angles of a triangle add up to 180 degrees

OpenStudy (anonymous):

its the same format right triangle means one of the angles is 90 and the other is 42 so subtract those two from 180 to get your number

OpenStudy (anonymous):

A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.

OpenStudy (anonymous):

90+42=132 180-132=48 so the missing angle is 48
