Question

Find the values for x and y

Answer 1

Look at the picture.

$x=90$

$\angle B\cong\anlge C\to m\angle B=m\angle C=47^o$

We know, the sum of the measures of the triangle is equal 180°.

Therefore in ΔBCD we have:

$y+47+90=180$

$y+137=180$             subtract 137 from both sides

$y=43$

Answer: x° = 90°, y° = 43°.
