3:4:5 = 3+4+5 = 12
660/12 = 55
55*3 = 165
55*4 = 220
55*5 = 275
person 1 = 165
Person 2 = 220
person 3 = 275
Answer:
x = 59.5
Step-by-step explanation:
the angles of a quadralateral equal 360 degrees, one angles is 90 degrees, the other i 151, 90 + 151 = 241, 360 - 241 = 119, 119/2 = 59.5, x = 59.5

Answer:
(x, y) = (5, 2)
Step-by-step explanation:
<u>Given</u>:
LP = x
MP = 2y+3
NP = y+3
KP = 3x -8
KP = MP, LP = NP
<u>Find</u>:
x, y
<u>Solution</u>:
The given relations between the segment lengths let us write two equations:
KP = MP
3x -8 = 2y +3 ⇒ 3x -2y -11 = 0 [eq1]
LP = NP
x = y +3 ⇒ x -y -3 = 0 [eq2]
__
Subtracting 3 times [eq2] from [eq1] gives ...
(3x -2y -11) -3(x -y -3) = 0
y -2 = 0 . . . . . . . . simplify
y = 2 . . . . . . . . . . add 2
Substituting this value into [eq2] gives ...
x = 2 + 3 = 5
The values of x and y are ...
x = 5, y = 2
