Step-by-step explanation:
The angles (8x + 28) and (4x - 7) are supplementary to each other so we can write
or

Also, note that the angle (4x - 7) and
are vertical angles, which means that they are equal to each other. Therefore,

Answer:
x plus 2 equals three x minus eight.
Answer: I think Figure D and A are congruent
Step-by-step explanation: Remember: congruent means the same (in geometry) so if im wrong. Then you could figure out for yourself which ones look the same. Good luck
Hello.
400=(x+20)x is the equation or 400=x^2+20x
<span>(x+10)=square root of 500
</span>
<span>so x+10=10 radical 5
</span>
<span>final answer -10 + or - 10 radical 5=x
</span>
Have a nice day
I believe that it’s this? y-y₁=m(x-x₁)
