Use exterior angles to show that the angle sum of quadrilateral PQRS is 360°.​
Shkiper50 [21]

Answer:

I don't really know but one triangle is 180 degrees so two added together is 360 degrees...

but ohh I remembered

a=c+d (since a+b=180 and c+d+b=180)

e=g+h (since e+f=180 and g+h+f= 180)

and the fact is that c+d+g+h+b+f=the angle sum of quadrilateral PQRS

a+e+b+f= the angle sum of quadrilateral PQRS (by substitutions)

a+e+b+f=360 (four angles are from one origin so it's 360 degrees )

F (x) = -3x + 2x – 5 Whatisf (-1)?​
eduard

Answer:

f(-1) = -4

Step-by-step explanation:

f(-1) simply means that what is f(x) when x = -1?

Just plug in -1 for <em>x</em> to find your answer:

f(-1) = -3(-1) + 2(-1) - 5

f(-1) = 3 - 2 - 5

f(-1) = 1 - 5

f(-1) = -4

the temperature at noon was -27 degrees . the temperature increased by 13 degrees by 2pm . what was the temperature at 2pm
Aleks [24]
First, you would create an equation for this problem. 
-27 + 13

Now, all you would have to do is solve it. 
-27 + 13 = -14

By 2 pm the temperature was -14 degrees. 

I hope this helps!
