Answer:
Please see the attached image.
Step-by-step explanation:
I'm assuming you've already learnt how to draw an equation in slope intercept form. The line of an inequality is drawn the same way.
The difference is that for inequalities you will have to shade.
Basically, the inequality sign will tell you which are to shade.
Greater than will mean above the line and
Less than will be below the line.
Also, if the sign is a "or equal to" sign, then the line will be solid, if not, it's dotted.

Answer:
m = 20°, n = 35°
Step-by-step explanation:
First, find n. We know that the base angles of an isosceles triangle are equal and that angles in a triangle add up to 180°. This means that:
- 110 + n + n = 180° - now simplify:
- 110 + 2n = 180° - subtract 110 from both sides:
- 2n = 180 - 110 - simplify again:
- 2n = 70° - divide both sides by 2:
- n = 35°
Now we know n, we can find m. The whole diagram is a triangle with angles of 90°, 35° (n) and the final angle can be split into m + n (m + 35°). This means that 125° + m + 35 = 180° (125 came from doing 90 + 35):
- 125 + m + 35 = 180° - now simplify:
- 160 + m = 180° - subtract 160 from both sides
- m = 180 - 160 - simplify
- m = 20°
Hope this helps!
