It will be a 360 degree angle
Answer:
No
Step-by-step explanation:
For x and y to have a proportional relationship, then
the ratio of k = 
must be equal for all points
(2, 5) → k = 
= 2.5
(3, 7.5) → k = 
= 2.5
(5, 12.5) → k = 
= 2.5
(18, 8) → k = 
= 2.25 ≠ 2.5
k is not equal for all values , hence no proportional relationship exists
Answer:
x=17
Step-by-step explanation:
Total cost of item = $138
Explanation:
The tax percentage = 15%
cost of item = $120
sales tax = cost of item × The tax percentage
sales tax = 120 × 15%
=120 × 0.15
sales tax = $18
Total cost of item = initial cost of item + sales tax
Total cost of item = 120 + 18
Total cost of item = $138

Step-by-step explanation:
Let a , b , c are three sides of a triangle
a : b : c = 3 : 4 : 5
a = 3x ,
b = 4x ,
c = 5x
a² = 9x²
b² = 16x²,
c² = 25x².
c² = a² + b²
by the pythagorean theorem,
a , b , c forms a right angled Triangle.
