) therefore OPTION C
yes it is right when the vertex of the first polygon is located on 3 - 2 after rotation the work vertex will be there on (2 , 3) it is right
Answer:(x-3)(x-3)
Step-by-step explanation:
Answer:
x = 6/7, y = 1/2
Step-by-step explanation:
7x + 2y = 7
-14x + 2y = -11
1) 7x + 2y = 7
2y = 7 - 7x
2) -14x + 2y = -11
-14x + 7 - 7x = -11
- 21x = -11-7
- 21x = - 18
x = 18/21 = 6/7
3) 2y = 7 - 7x = 7 - 7*(6/7) = 7 - 6 = 1
2y = 1
y = 1/2
Answer:
2 km
Step-by-step explanation:
Reference angle = 45°
Opposite = u
Hypotenuse = 2√2 km
To find u, apply SOH:
Sin 45° = Opp/Hyp
Sin 45° = u/2√2
√2/2 = u/2√2 (sin 45 = √2/2)
Cross multiply
2*u = √2*2√2
2u = 4
Divide both sides by 2
u = 4/2
u = 2 km
