Answer:
I think option B i.e. when its angles are right angles.
Ask me your other questions.i hope it was helpful
The partial circles in each corner mean that all 3 angles are identical, which means this is an equatorial triangle. In an equatorial triangle all three sides are the same.
We can set two of the equations to equal each other and solve for x:
3x -5 = 2x +20
Add 5 to each side:
3x = 2x +25
Subtract 2x from each side:
x = 25
The answer is Abecause if you plug in the value es for each function A is the only one the makes it trye
