I don’t know i never seen this math problem before
Answer:
The answer is Graph X.
- Always start by isolating the variable \color{red}y on the left side of the inequality.
- Change the inequality to equality symbol.
- Graph the boundary line from step 2 in the XY-plane.
- The last step is to shade one side or region of the boundary line.

Answer: 5
Step-by-step explanation:
∡b is a vertical angle to ∡a and therefore a twin, and we know that ∡a = 120°, thus since ∡b = ∡a, ∡b = 120° as well.
a full circle has a total of 360°, ∡d and ∡c are vertical angles, namely two angles across from each other at a junction, and therefore ∡d = ∡c.
∡a + ∡b is 120° + 120° thus 240°, since a circle has a total of 360°, 360 - 240 = 120, so the other two angles pick up that slack and divide it among each other evenly, 120/2 = 60, so ∡d = ∡c = 60°.
Hope the picture will help you...
