Answer:

x=61 -> Figure A

x=27 -> Figure B

x=12 -> Figure C

Step-by-step explanation:

For A:

x=61 because the line going through the shape cuts in angle into 2 congruent angles

For B:

The corner adds up to 90 because it a rectangle, and rectangles only have right angles.

So: 2x+10+x-1=90

Solve.

3x+9=90

3x=81

x=27

For C:

The two given angles should add up to 90.

4x+10+2x+8=90

Solve.

6x+18=90

6x=72

x=12
