Answer:
x = - 4
Step-by-step explanation:
Sum of interior angles in a triangle = 180
so
x + 24 + 20 + 140 = 180
x + 184 = 180
x = - 4
Answer:
-4
Step-by-step explanation:
The total degree of a triangle is always 180.
20 + 140 + 24 + x = 180
now we simplify and relocate some numbers to the other side of the equal sign.
20 + 140 = 160
160 + 24 + x = 180
24 + x = 180 - 160
24 + x = 20
x = 20 - 24
x = -4
<u>check</u>
20 + 140 + -4 + 24 = 180
