To find the value of \( x \) in a triangle where the angles are \( 40^\circ \), \( 60^\circ \), and \( x \), you can use the Triangle Sum Theorem. This theorem states that the sum of the angles in a triangle is always \( 180^\circ \).
So, the equation you can use is:
\[
40 + 60 + x = 180
\]
Now, you can simplify and solve for \( x \):
\[
100 + x = 180
\]
Subtract \( 100 \) from both sides:
\[
x = 180 - 100
\]
\[
x = 80
\]
Therefore, the value of \( x \) is \( 80^\circ \).
So, the equation you can use is:
\[
40 + 60 + x = 180
\]
Now, you can simplify and solve for \( x \):
\[
100 + x = 180
\]
Subtract \( 100 \) from both sides:
\[
x = 180 - 100
\]
\[
x = 80
\]
Therefore, the value of \( x \) is \( 80^\circ \).
