Based on estimation, it should be the fourth choice. Hope this helps!!!
Step-by-step explanation:
yes that's true
if a^n=b
then
a^n/n=b^1/n
a=b^1/n
M∠ADB + m∠BDC = m∠ADC [<span>angle addition postulate]
x + x + 10 = 60
2x + 10 = 60
2x = 60 - 10
2x = 50
x = 50/2
x = 25
a
m</span>∠ADB = x = 25°
b
m∠BDC = x + 10 = 25 + 10 = 35°
Lol I’m not sure but I’m logging in so it’s making me “answer”
