The answer is approximately141.3
When at least one of the factors still has a common factor
BD is a angle bisector and Angle bisector theorem says
ratio of other sides of the triangle formed by bisector is equal
BA/AD=BC/CD
lets say AD is x so DC will be 4-x
3/x=4.5/4-x
x=1.6
AD=1.6units
so DC=4-x=4-1.6= 2.4 units
Answer:
what the hecker is that.
okay so your simplifying it, 12? i think.
4 is correct with the perfect reasoning.
5 says SRT is the same as STR
So SRT = 20
STR = 20
Now if STR is 20, then STU has to be 160 because the two angle have to add up to 180 to make a straight line
So 160 has to equal 4X
4x=160
X=40
