Answer:
36
Step-by-step explanation:
Answer:
D. M<6 + M<10 = 180°
Step-by-step explanation:
Because they are consequetive interior angles and they are supplementary
Answer:
Step-by-step explanation:
4*3^x+1=27+(3^2)^x
(3^2)^x=(3^x)^2
3^x=t
4t+1=27+t^2
t^2-4t+27-1=0
t^2-4t+26=0
delta=4^2-4*1*26=16-84=-68<0
the equation has not real solutions
M∠ADB + m∠BDC = m∠ADC <span>
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°

Angle Addition Postulate
49, because 7 one sevenths in a pounds, so 7x7=49 :)
