Answer:
At first we should know that:
<u>The properties of the square are:</u>
- It has four equal sides.
- All angles are right angles or equal to 90º.
- The sum of its all angles is 360º
- It has two pairs of perpendicular lines.
- It has two pairs of parallel lines.
<u>The properties of Rhombus</u>
- It has equal four sides.
- The opposite sides are of the same length.
- It has two acute angles and two obtuse angles.
- The sum of its all angles is 360º
- It has zero pairs of perpendicular lines.
- It has two pairs of parallel lines.
So, Wade is incorrect because the quadrilateral may be <u>Rhombus</u>
And the quadrilateral to be a square, she needs to show that It has two pairs of perpendicular lines.
First you find out what 20% of 30 is (30 * 0.20 = 6)
Then you take 30/6 to get your answer (30/6 = 5)
There will be 5 students in each group.
Answer:
6
Step-by-step explanation:
Straight line is 180
square = right angle=90
180-90=90
5x+(x+54)=90
6x+54=90
6x=36
x=6
Hope this helps :D
Answer:
Solution: (-4, 2), x= -4 and y =2
Step-by-step explanation:
-8x - y = 30
-2y = x
Substitute for x
-8*(-2y) - y = 30
16y - y = 30
15y = 30
y = 30/15 = 2
Then x = -2y = -2*(2) = -4
Solution: (-4, 2), x= -4 and y =2
