Question

if an angle is 30 degree more thanonehalf of its complement, ifnd the mesure of the angle

Answer 1

Let the angle be x^o and hence its complement will be (90 – x)^o whose one-half means (90 – x)^o/2 .
According to the data given:
x = 30 + (90 – x)/2
or 3x = 150
or x = 50

Hence the angle measures 50^o.
