Answer:
the largest angle of the field is 149⁰
Step-by-step explanation:
Given;
perimeter of the triangular filed, P = 120 m
length of two known sides, a and b = 21 m and 40 m respectively
The length of the third side is calculated as follows;
a + b + c = P
21 m + 40 m + c = 120 m
61 m + c = 120 m
c = 120 m - 61 m
c = 59 m

Consider ABC as the triangular field;
Angle A is calculated by applying cosine rule;

Angle B is calculated as follows;

Angle C is calculated as follows;

Therefore, the largest angle of the field is 149⁰.
No solution simply because the expression cannot be solved with rational numbers
Answer:
The answer to your question is C. 3.2
Step-by-step explanation:
| 3.2 |
lines | | mean absolute value, and absolute value means the distance of a number to the origin (0,0) it does not matter the sign.
Then to answer your question just do not write the | | and consider it as a positive sign.
If your question had a negative number ex. | -3.2 | the answer would also be 3.2.
