well by bisecting <ABC  

the angles formed  <ABD and <DBC  are equal

so equate the equations 

5x = 3x + 10

solve for x

then you will be able to find the measure of angles or value of x

jessiegonzales · Answer

is it 5?

campbell_st · Answer

well x = 5   I don't know if you just needed to find x or find the angle measure...

jessiegonzales · Answer

it says find m<ABC so thats 5? @campbell_st

campbell_st · Answer

ok... so if x =5 

then you have the 2 equation 

5x 

and 

3x + 10

substitute and then add the angle measures together to get the measure of <ABC

campbell_st · Answer

the 2 smaller angles must add to the larger angle...

jessiegonzales · Answer

so the two smaller angles combines makes 30* right? @campbell_st

campbell_st · Answer

well not quite 

5 * 5 = 25

and 

3*5 + 10 = 25

so the measure of <ABC = 25 + 25

Thanks so much so the answer is 50?
