It is useful to determine the distance the swing is below the pivot point when it is at its highest point of travel. That distance is

... 7 m + 0.8 m - 3.4 m = 4.4 m

The the cosine of the angle of interest is

... cos(θ) = 4.4/7

... θ = arccos(4.4/7) ≈ 51.055°

The angle is about 51°.

kondaur [170]

Answer:

the answer is b

Step-by-step explanation:

they should have the same slope so just looking at that you cancel out d. But since it says has a y-intercept of 1 then it would cancel out the other 2. d is perpendicular to it not parallel

I WILL AWARD BRAINLIEST!! PLEASE HELP!!

Answer:

m∠EBC=65° 15' and AC=20in

Step-by-step explanation:

Given:

AB≅BC

AE=10in\\m\angle FEC=90\\m\angle ABC=130\°30'

From the given Data, we can conclude the following:

1. Since two sides of the triangle ABC are congruent, therefore its an isosceles triangle.

2. m\angle FEC=90°. This shows that the line BE is perpendicular to AC. By property of isosceles triangle, the line which passes from the vertex of the largest angle of triangle and cuts the opposite side(base) perpendicularly is the perpendicular bisector of the side and angle bisector of the angle.

∴  m\angle EBA\ ≅m\angle EBC    [ Definition of Angle bisector]

m\angle ABC=130\°30'

m\angle EBC=\frac{m\angle ABC}{2}=\frac{130\°30'}{2}=65\°15'

m\angle EBC=65\°15'

∴AE=EC       [ Definition of perpendicular bisector]

AE=EC=10in

AC=AE+EC

AC=10+10=20in

AC=20in
