The answer is 68 degrees because that angle is half of the 136 angle.
Yes, if you are counting intercepts are both x and y-intercepts.
A third degree polynomial would only have 3 x-intercepts. However, it could also have a y-intercept. This would make the total number of intercepts 4.
If you want the ratio in its simplest form, then it’s already in its simplest form.
The value of ∠EBD is 66°
<h3>Vertically opposite angles</h3>
Vertical angles are a pair of opposite angles formed by intersecting lines. Vertical angles are equal. Therefore,
∠EBA≅∠CBF
Therefore,
∠EBA = 40 - x
∠EBA + ∠EBD = 90°(complementary angles)
Therefore,
40 - x + 6x - 30 = 90
5x = 90 + 30 - 40
5x = 80
x = 80 / 5
x = 16
Therefore,
∠EBD = 6(16) - 30 = 66°
