can you tell me how you got the answers to it

563blackghost · Answer

You first need to analyze the diagram....

We see that BC is bisected by line AD this would mean that the angles on either side of D it is 90 degrees.

bmxlifestyle · Answer

ok

563blackghost · Answer

Since we are indicated that two sides are congruent this would mean that this triangle is an isoceles triangle which tells that there a two angles and sides that are congruent. So angle C is congruent to angle B. So angle B is 47 degrees.

563blackghost · Answer

So we now know of two angles in one part of the triangle. So to find y we would add up the two angles and subtract by 180.

$\huge\bf{180-(90+47)=y}$

bmxlifestyle · Answer

what about x

bmxlifestyle · Answer

so y = 137 ?

This is how you find x.

563blackghost · Answer

Make sure to add `90 and 47` and then subtract `180 by 137` to find y.

bmxlifestyle · Answer

y = 43
