HELP ME PLEASE AND EXPLAIN IT TOO! 28 Points!!!!!!!!!!
SIZIF [17.4K]
X=4
First find the solution to (x+1) ft. I chose to guess the answer as 4 and it worked (you’ll have to guess). I then plugged 4 into the other equation 2x. It became 2•4. Solving give the side length of 8 ft. Then you have to check to make sure they both have the same area. To do this just solve the equations.
First rectangle- 4•4= 16 ft area
Second rectangle- 2•8 = 16 ft area
( I’m really sorry if this is confusing)

A ray bisects an obtuse angle into 2 congruent angles. what type of angle are those 2 congruent angles
VikaD [51]
A. An obtuse angle is less than 180 but greater than 90. So for examples sake I will use 179 degrees. 179 divided by 2 (as the angles are congruent) = 89.5 which is less than a right angle. Therefore, the angles will be acute.

Hope it helps :)
