The first side is 10 inches
the side parallel to this is (10×2)= 20 inches
Height is half the length=1/2×20=10 inches
The area of trapezium is given by:
Area=1/2×h×(a+b)
where a and b are the sides, h is the height. Thus the area will be:
Area=1/2×10×(20+10)
=1/2×10×30
=150 sq. inches
Answer:
<h2>11/19</h2>
Step-by-step explanation:
= 11/19
The answer is -7
The arrows both point toward the left side, and sine there are seven spaces the arrows are going through, you subtract 7 spaces and get -7
Hope that helps.
Answer:
x = -3, y=2
Step-by-step explanation:
x+3y =3
3y -2x =12
Solve the first equation for x
x = 3-3y
Substitute this into the second equation
3y -2(3-3y) =12
Distribute
3y -6 +6y =12
Combine like terms
9y -6 =12
Add 6 to each side
9y-6+6 =12+6
9y =18
Divide each side by 9
9y/9 =18/9
y = 2
Now find x
x = 3 -3y
x = 3-3(2)
x = 3-6
x = -3
Answer:
The answer to your question is: x = 100
Step-by-step explanation:
It's a polygon of 7 sides
The sum of internal angles in a polygon equals 180(n-2), where n = # of sides
Internal angles = 180(7-2)
= 180(5)
= 900°
(x + 50) + (x + 50) + (x + 50) + x + x + x + (x + 50) = 900
4(x + 50) + 3x = 900
4x + 200 + 3x = 900
7x = 900 - 200
7x = 700
x = 700 / 7
x = 100
