C. 42.39 times 0.1 is 4.239. 42.39-4.239= 38.151 which rounds to 38.15

Answer:
(190-5a)°
Step-by-step explanation:
Sum of internal angles of a triangle equals to 180°
If the third angle is x, then we have:
- (2a-32)°+(3a+22)° +x = 180°
- (5a- 10)° +x= 180°
- x= (180+10-5a)°
- x= (190-5a)°
The third angle is: (190-5a)°
In order to determine the expression that should be multiplied to n^2 to get 5n^3, divide 5n^3 by n^2. First for the numerical coefficient, 5 divide 1 is 5. For the variable n, n^3/n^2 is n. Thus, the term that should be multiplied to n^2 is 5n.
