Step-by-step explanation:
phukan = x
Nanwan = y
let this be a simultaneous equation.
x - y = 18.... equation i
x + y = 100.... equation ii
subtract equation i from equation ii
= 2y = 118
y = 59
substitute y = 59 in equation ii to get x
x + 59 = 100
x = 100- 59
x = 41
Nanwan = 59, Phukan = 41
It would be 4.8333333333.
The three repeats here.
Answer:
Step-by-step explanation:
Given:
bisects angle BAC
Triangle ABC is isosceles triangle, because 
Angles adjacent to the base of isosceles triangle ABC are congruent.
Hence,
The sum of the measures of all interior angles is 180°, so,
Since bisects angle BAC, angles BAD and CAD are congruent by definition of angle bisector. So,
AD ia angle bisector in isosceles triangle drawn to the base, so it is the height. Thus, AD and BC are perpendicular. So,
O * o
