Answer:u
Step-by-step explanation:
360°÷n = number of sides of a regular polygon.
n= one of the exterior angle of a regular polygon.
180°-60°=120°
n=120°
360°÷120°= 3
Answer:
(6, -
)
Step-by-step explanation:
Given the 2 equations
3x - 4y = 20 → (1)
4x - 2y = 25 → (2)
Multiplying (2) by - 2 and adding to (1) eliminates the y- term
- 8x + 4y = - 50 → (3)
Add (1) and (3) term by term to eliminate y
- 5x = - 30 ( divide both sides by - 5 )
x = 6
Substitute x = 6 into either of the 2 equations and evaluate for y
Substituting into (1)
3(6) - 4y = 20
18 - 4y = 20 ( subtract 18 from both sides )
- 4y = 2 ( divide both sides by - 4 )
y =
= - 
Solution is (6, -
)
