Answer:
70
Step-by-step explanation:
You know the inside of a tringle has a total of 180 degrees. You also know that the angle V sits on a plane that is also 180.
Start by getting the value of angle V, so 180-120 = 60
With that, you can find angle U. Set up your formula as
U = 180 - 50 (Angle T) - 60 (Angle v)
U = 180 - 50 - 60 = 70
You can apply the same knowledge to the other questions as well.
A scale of 1:50 000 means that every centimetre on the map is equal to 50 000 centimetres (500 metres) in reality.
The distance between two towns on that map is 6cm, therefore in reality there’s 6 * 50 000 = 300 000 centimetres, which is equal to 3 000 metres, which is equal to 3 kilometres.
Answer:
the rate of change is 1/2
Step-by-step explanation:
The rate of change is described by the change in y over the change in x. I'm guessing you meant to put an x after 1/2. The equation you wrote is in y-intercept form, as it gives us the slope and y-intercept. Slope is the same as rate of change. In simple terms, the number beside x is the rate of change. 1/2
6. 7 is half of 14 and 6 is half of 12.
