See the attached figure to better understand the problem
we know that
in the triangle ABC
tan(alfa/2)=AC/BC----> 5/3
so
(alfa/2)=arctan (5/3)---------> 59.0362°
alfa=2*59.0362--------> alfa=118.07°
alfa+beta=180°----------> because are supplementary angles
beta=180-118.07-------> beta=61.93°
the answer is
the angles are
alfa=118.07°
beta=61.93°
Answer:
The correct answer is $12
Step-by-step explanation:
To check, subtract 12 from 31
31 - 12 =19
Multiply 19 by 2
19 x 2 =38
Add 12
38 + 12 =50
1) 50*50, our 2500
2) 1500
3)1500
4) 900
just multiply t the number of people by the amount each pays
