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 )

Hi there!

For these two equations, we would be using PEMDAS...

$3$ · $3=9-5=4$

$5$ · $6=30+19=49$

Hope this helps!

5-(-4)=5+<br> write as addition

Furkat [3]

Answer:

$5+4$

Step-by-step explanation:

Based off the typical rules of integers, expressions like these can be simplified to look different but mean the same thing.

$5 - (-4) = 5+4$

In this case, we subtracted a negative value from a positive value; by doing this, we actually added positive 4.

Based on the same principals, adding a negative number is equivalent to subtraction!

Any time you see equations similar to this, you want to cancel out the 2 negative signs to make it positive!

Please look at the attached file for more information :)

Answer:

<h2> C. 5, 2, Tails is not a possible outcome</h2>

Step-by-step explanation:

We are presented with three items

two dices and a coin

The sample space for a dice is S=(1,2,3,4,5,6)

and the sample space for a coin is S=(head and tail)

In the options provided all are possible outcomes for the two dices and the coin except for options "C" ,and this is because "8" is not a sample space in a dice
