Hey there! :D

If m<A is the vertex, and it is isosceles, then the last two angles are equal. 

All the angles in a triangle equal 180 degrees.

180-140= 40

40/2= 20

m<b=  20 degrees. 

I hope this helps!

Which statement describes the mapping?
icang [17]

Answer:

Third one

Step-by-step explanation:

To be a function x must only have 1 y value or you're really describing a limit which isn't part of the outputs

However, In your case two x values equaling the same y value is fine because the x values do not have two y values

This is a function, as each x value corresponds to one y value

My apologies I was confused with my first answer.

In Mrs Phillips math class the ratio of boys to girls is 4 to 2. If there are 51 girls in math class, how many boys are there?
maksim [4K]
So for every two girls, there's four boys. There are twice as many boys than girls, so the number of girls • 2 = your answer.

51 • 2 = 102
