It is 1. 2 and 3 are base angles.
Use simple unitary method:
∵ 1.5 cm on map = 25 miles in reality
∴ x cm on map = 190 miles in reality
![\frac{1.5}{x} = \frac{25}{190}\\ x = 11.4 cm](https://tex.z-dn.net/?f=%5Cfrac%7B1.5%7D%7Bx%7D%20%3D%20%5Cfrac%7B25%7D%7B190%7D%5C%5C%20x%20%3D%2011.4%20cm)
Thus, the two cities are 11.4 cm apart on the map
Answer:
4
Step-by-step explanation:
The number of edges connecting to that vertex is 4. (It doesn't matter that two of them both go to vertex A.)
Vertex E has degree 4.
Answer:
C
Step-by-step explanation:
we have to solve the associated equation:
(x+5)(2x-8) = 0
a product is equal to 0 if at least one of its factors is equal to 0
so we can solve this two equations
x + 5 = 0 x = -5
2x - 8 = 0. x-4 = 0 x = 4
Answer: Well, do you mean the whole value? If so... it's two-hundred and eighty. If you mean the individuals, then the two is two-hundred, the 8 is eighty.
