Answer: x = 
Step-by-step explanation:
The exterior angle of a triangle = sum of the opposite interior angle.
The interior angles given are : 
and 
Which are opposite to x + 72
Therefore :
x + 72 = +
x + 72 = 
x = - 
x =
Answer:
720 cm^3
Step-by-step explanation:
Answer:
20°
Step-by-step explanation:
A triangle = 180°
∴ 180° -120°-40°
=20°
The normal body temperature : to = 37° C
An inequality is:
| t - to | ≤ 3
| t - 37 | ≤ 3
t - 37 ≤ 3 AND ( - t - 37 ) ≤ 3
t ≤ 3 +
37
- t + 37 ≤ 3
t ≤
40
- t ≤ 3 - 37
- t ≤ - 34 / *( - 1 )
t ≥ 34
