Answer:
X=38
Step-by-step explanation:
this is an isosceles triangle as we can see by the lines on the sides of the triangle. that means both of those sides are equal to 52.
52x2=104
A triangle adds up to 180. If two of the sides already equal 104 then the last side will be how much will go up to 180.
180-104=76
It is cut by a bisector DB meaning both sides will be equal. So divide 76 by 2 and we get 38
I can't really tell if x is for one side of angle b or both sides. If it is only for one side then it is 38 but if it is for the whole angle B then it is 76.
