Answer:
see the explanation
Step-by-step explanation:
see the attached figure to better understand the problem
we have that
OA+OB=radii of circle O
Point P is equidistant from radii OA and OB ----> given problem
so
PA=PB
OP is a common side
Triangle OAP is congruent to Triangle OBP by SSS Postulate Theorem
Remember that
If two triangles are congruent, then its corresponding sides and its corresponding angles are congruent
That means
![m\angle POA=m\angle POB](https://tex.z-dn.net/?f=m%5Cangle%20POA%3Dm%5Cangle%20POB)
therefore
The radius from the point (PO) bisects the angle formed by the two given radii (angle ∠AOB)
<span>let number of hours of Isaac,Ruby and Svetlana worked be x,y and z respectively.
so y= x+6 ( equation 1)
note: Ruby (y) worked 6 hours more than Isaac (x)
z = 4 x y ( equation 2)
note : Svetlana (z) worked 4 times as many hours as Ruby (y)
x+y+z= 126 ( equation 3)
note: Together they (x,y,z) worked 126 hours.
substitute eqn 1 to eqn 3
so x+y+z= 126 becomes
y-6 + y+z-126
2y+z= 126+6
2y+z=132 (equation 4)
the substitute eqn 2 in eqn 4
so 2y+z=132 becomes
2y+4y=132
6y=132
y=132/6= 22
so y=22
substitute y value in equation 1
so y= x+6 becomes
x+6=22 and
x= 22-6 = 16
and substitute x and y values in equation 3
so 16+22+z= 126
38+z= 126
z= 126 -38 = 88
So the number of hours Isaac worked (x) is 16 hours
number of hours Ruby worked (y) is 22 hours
number of hours Svetlana worked (z) is 88 hours</span>
