Answer:
If you were to move five to the other side, the equation would have a completely different outcome. Instead of x + 5 = 27 it would be x = 27 + 5. Then the answer would be x=32 rather than x=22. You need to do the inverse of the original equation to get the correct solution. (AKA: balancing the equation)
I hope this helps :))
That square in a means that it’s 90 degrees and b is 70. Well it says that ab = bc. And ab together is 90+70 which is 160. A straight line is 180 in total so to figure that other side of b out do 180-70 which is 110. So now you have 110, and to match ab you need 50 more degrees for bc. Therefore c is 50 degrees
Answer:
D. 12
Step-by-step explanation:
<A = <C = 50. It's isosceles triangle
So AB = BC
Plug in
4x = 2x + 6
2x = 6
x = 3
AB = 4 (3) = 12
