Answer: 28
explanation: a= 8(7)/2 = 28
hope this helps :)
Supplementary angles add to 180
4+5=9
180/9=20
4*20=80
5*20=100
the angles are 80 degrees and 100 degrees
Part A: x=2
This would make both perimeters equal to 24.
Part B: No solution.
You cannot make x equivalent to anything but 2, or the square would not be real. All four sides of the square must equal 6. This would make the area 36 units squared. If x was 2 for the rectangle, the area would be 20. It is impossible to make them equal. Tell me if I'm wrong, though.
Answer:
x = - 18
Step-by-step explanation:
Let certain number = x
<em>The difference between half of a certain number and seven</em>
x/2 - 7
<em>is the same as</em>
=
<em>with adding two to that number</em>
x + 2
<em>Find the number</em>
x/2 - 7 = x + 2
x - x/2 = - 7 - 2
( 2x - x ) / 2 = -9
2x - x = -18
x = - 18
