Question

Find m<ADB
a) 59°
b) 44°
c) 13°
d) 33° ​

Answer 1

A) 59°

Explanation:

m<ADC is a right angle, therefore it is 90°

so that means you can now subtract the angle that you already know [31°] from it to get the angle that is left over, m<ADB

90°-31°= 59° (subtracting m<ADC [90°] from m<BDC [31°] leaves your remaining angle m<ADB [59°]
