ABC Dis a rhombus. If ABC = 40°, then ADCis equal to​

Answer 1

Hi mate

Since <ACB = 40 deg, <BCD = 2*<ACB = 80 deg. <ADC = 180-<BCD = 180–80 = 100 deg, so <ADB = 100/2 = 50 deg.

Answer 2

Step-by-step explanation:

Since <ACB = 40 deg, <BCD = 2*<ACB = 80 deg.

<ADC = 180-<BCD = 180–80 = 100 deg,

so <ADB = 100/2 = 50 deg.
