Answer:

x = 35

y = 7

Step-by-step explanation:

See how the image looks like two overlapping triangles. It is given that the triangles are congruent. Its easier to see whats what if you draw the triangles separately. I also flipped over the triangle on the right so they match. Record the given angle measures. Since A is 45° then D is also 45°. DBC is 30°, so we can find the missing angle in triangle DBC. Angles in a triangle add up to 180° so

C + 45 + 30 = 180

C + 75 = 180

C = 105°

This is angle DCB.

Now all the angles are marked. We can set up equations to find x and y. see image.

irga5000 [103]
To solve for x, add 3 to both sides, multiply both sides by -1, then take the square both sides.
3- \sqrt{x} =0\\- \sqrt{x} =-3 \\  \sqrt{x} =3 \\ x=3^2=9
