If you imagine a coordinate plane, there are 4 sections.
1 : (+,+)
2 : (-,+)
3 : (-,-)
4: (+,-)

Now, point (4,-7) is in the 4th section. Meaning, the reflection over the y-axis would be in the 3rd section. It would be (-,-)

The reflection over the y-axis of (4,-7) is (-4,-7).

I hope this helps!

In Δ,∠=70°,∠=50° ∠ . <br> ℎ ∠.
AveGali [126]

Answer:

100°

Step-by-step explanation:

A triangle is a polygon shape with three sides. Triangles are of different types such as obtuse, scalene, equilateral, isosceles etc.

In triangle ABC:

70° + 50° + ∠C = 180° (sum of angles in a triangle)

120 + ∠C = 180

∠C = 180 - 120

∠C = 60°

Since ∠C is bisected into ∠ACD and ∠BCD, hence:

∠ACD = ∠BCD = ∠C / 2

∠ACD = ∠BCD = 60 / 2

∠ACD = ∠BCD = 30°

In triangle ACD:

∠A + ∠ACD + ∠ADC = 180° (sum of angles in a triangle)

50 + 30 + ∠ADC = 180

∠ADC + 80 = 180

∠ADC = 100°
