How many right angles can be in an obtuse angle?

Only one angle can be right angle in obtuse angle
because if there are two right angles are in an obtuse angle it would be180  that doesn't make sence

One angle as right angle

Hello!

To graph the solution x>-2 on a number, the first thing you need to do is to mark -2 on the number line using an open circle.

The reason you would use an open circle (like o instead of •) is because the symbols > and < represent a solution that is greater than or less than the number, but does not include it. In the case of x>-2, the solutions are all greater than than -2 but because the symbol does not state x can be -2 (if it were you would be using ≥ which states x can be any number greater than or equal to -2) all values of x are any numbers that are greater than -2 such as -1, 0, or 5.

Then, once you have plotted the open circle on -2, because all your solutions are greater than -2, draw a line on the number line (make it bold if you have to) going towards the right to show this.
