Answer:
b = 60
Step-by-step explanation:
The sum of the angles of a triangle are 180
80+40+b = 180
Combine like terms
120+b =180
Subtract 120 from each side
b = 180-120
60°
Recall that all triangles have an interior angle sum of 180. In other words:
Plug in the angle values we know:
6-6x= -24
Subtract 6 from -24 = -30
divide -30 by -6= 5
x=5
25,000
i think because 10 times 100 gets 1000 so now you have to do 250 times 100 to get 25,000
