Answer:

$90x$

Step-by-step explanation:

$30x+60x=?$

If you want to solve this easily, you can just remove x and add 30x + 60x.

$30+60$

We know that 30 + 60 is 90. So we will add x to 90.

$90x$

Now you have your answer!

Hope this helps!

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 )
