find the values of x and y.

x = 90 degrees, y = 43 degrees

Step-by-step explanation:

Given: <C = 47 degrees

AB = AC

To find: x and y

proof:

in triangle ABC,

AC=AB

So, <B=<C=47 (angles opposite to equal sides of a triangle are equal)

<B=47 degrees

In triangle ABC,

<B + <C + 2y = 180 (angle sum property)

47 + 47 + 2y = 180

94 + 2y = 180

2y = 180-94

2y = 86

y = 86/2

y = 43

In triangle ABD,

<B + y + x = 180 (angle sum property)

47 + 43 +x = 180

90 +x = 180

x = 180-90

x = 90

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

-2 is the right
