Find the values of x and y

a) 90, 43

b) 90, 47

c) 43, 47

d) 47, 43

As this is an iscosoles triangle, the other corner of the full triangle will be 47. So 47+47=94. There are 180 degrees in a triangle so 180-94=86. But you want to find half of that so 86÷2=43. 'Y' = 43. Now to find 'x' you need to add 47 and 43 together which makes 90. So 180-90=90 so 'X' = 90. So the answer is A ; 90,43.
