Answer :
Answer:
A) 156 Degrees
Step-by-step explanation:
All angles in a triangle ALWAYS adds up to 180°.
Step 1: Set up equation
12° + 12° + x° = 180°
Step 2: Solve for x
- Combine like terms: x° + 24° = 180°
- Subtract 24° on both sides: x° = 156°
Step 3: Check
All angles should add up to 180°. Plug it in and check.
156° + 12° + 12° = 180°
156° + 24° = 180°
180° = 180°
Answer:
A
Step-by-step explanation:
We know that the sum of the interior angles of a triangle must equal 180°. So:
[tex](12)+(12)+x=180[/tex]
Solve for x. Add on the left:
[tex]24+x=180[/tex]
Subtract 24 from both sides:
[tex]x=156\textdegree[/tex]
Our answer is A.
And we're done!
