<u>Answer:</u>
<u>Step-by-step explanation:</u>
The sum of interior angles of a quadrilateral is 360°.
If we consider the measure of one of the unknown angles to be 
°, we can set up the following equation:
Now we can solve for :
⇒ 
⇒ 
[subtracting 192° from both sides]
⇒ 
⇒ 
[dividing both sides by 2]
⇒ 
Therefore, the other two angles each have a measure of 84°.
Around 14.40 would be the answer
Maybe it's length x width x height? So you'll do 11x5x8= 440
Two perpendicular lines have slopes that are negative reciprocals of each other, that is, if one slope is a/b, the other is -b/a
the first line 5x+2y=20, 2y=-5x +20, y=-5/2 x+10, the slope is -5/2, so the perpendicular line's slope is 2/5
the equation in point-slope form is (y-2)=(2/5)(x-5)
in slope-intercept form: y=(2/5)x
in standard form: 2x-5y=0
Answer:
You just get the number (lets say 2) and you basically add two two times. So two plus two is 4.
It is simple, unless you want to do big digit numbers. Then you have to memorize the times tables.
