The answer for both questions are adult humans
The opposite side pairs in a rectangle are congruent, so basically QT would be congruent to RS when you draw the rectangle and label the points.
4x+10=30
4x=20
x=5
Answer: 
Step-by-step explanation:
1) Multiply the first equation by 3,and multiply the second equation by -5: 
, 
2) Simplify: 
, 
3) Add the equations to eliminate 
: 
4) Divide both sides by 
: 
5) Simplify: 
6) Substitute 4 for x in 
: 
7) Simplify: 
8) Subtract 
on both sides of the equation: 
9) Divide both sides by 
: 
10) Simplify: 
11) Write point:
Answer:
Step-by-step explanation:
1) 97 + x = 64 + 27 {Exterior angle property}
97 + x = 91
x = 91 - 97
x = -6
2) 4x + 17 + 80 + x + 23 = 180 {Angle sum property of triangle}
4x + x + 17 +80 + 23 = 180
5x + 140 = 180
5x = 180 - 140
5x = 40
x = 40/5
x = 8
You can't find a value of x since there is no equal sign. This is not an equation. It is just an expression, so you can't solve it for x.
