Answer:
Perimeter = AB + AC + BC = 26.55 units
Step-by-step explanation:
The perimeter of a triangle is the sum of lengths of all sides.
Here we have a right triangle, right-angled at C
angle B = 46°
AB = 11
We continue to calculate
AC = (11)sin(46°) = 7.91
BC = (11)cos(46°) = 7.64
Perimeter = AB + AC + BC = 26.55 units
Answer:
The number of teacher who joined the school is 20
Step-by-step explanation:
Teacher : Students = 1 : 16
Number of teachers = 1x
Number of students = 16x
16x = 1600
x = 1600/16
x = 100
Number of teachers at the beginning = 100
Now, after some teachers (let it be y) joining the school,
Teacher : students = 3:40
The number of teacher who joined the school is 20
