Answer:

1.ABC = 45°,DBE = 45°. ABD = 135°,CBE = 135°

2.ABC = 62°, DBE = 62°, ABD =118°,CBE = 118°

Step-by-step explanation:

1.angle ABC = angle DBE because they are vertical. You can write the equation 3x+38 = 5x+20 and find both angles. When you solve, x=9. You substitute it in. ABD is equal to 180-45° because it is supplementary with ABC. ABD = CBE b/c vertical angles.

2.You do the same thing. 4x+2=5x-13,x=15. You substitute in 15 for x and get 62°. They are the equal angles. For ABD you do 180 -62 since they are supplementary angles, which gets you 118 which applies for both because they are vertical angles.

Answer:

A. 46.1 ft

Step-by-step explanation:

You need to look at this scenario as a triangle, with the object, Eric and Aaron being 3 different points.

<u>Refer to the attached image for clarity.</u>

To solve this, we will use the Sine Rule.

To apply this, we need to know two angles that correspond to the side of the triangle opposite of them, and the length of those to sides.

<h3><u>Finding the unknown angle</u></h3>

The sum of a triangle is 180 degree, and we can subtract the value of the known two angles from this to obtain the value of the unknown angle (A)

180 - 35 - 50 = 95 degree

<h3><u>Apply Sine Rule</u></h3>

To solve for the distance between Eric and the Object, we will apply this as follows:

Sine A / a = Sine C / c

<em>Note: We are using the angle C because the corresponding angle directly opposite is the side of the triangle we need to find</em>

Sine 95 / 80 = Sine 35 / c

Rearrange the equation

c = Sine 35 x 80 / Sine 95

c = 46.06

c ~ 46.1 ft

In a simplified model of a hydrogen atom, the electron moves around the proton nucleus in a circular orbit of radius 0.53 × 10−1

tresset_1 [31]

For the answer to the question above,
<span>a) Use F = k * q1 * q2 / d²
where k = 8.99e9 N·m²/C²
and q1 = -1.602e-19 C (electron)
and q2 = 1.602e-19 C (proton)
and d = distance between point charges = 0.53e-10 m
The negative result indicates "attraction".

b) Here, just use F = ma
where F was found above, and
m = mass of electron = 9.11e-31kg, if memory serves
a = radial acceleration

c) Now use a = v² / r
where a was found above
and r was given

d) period T = 2π / ω = 2πr / v
where v was found above
and r was given </span>

What is the solution set

netineya [11]

The answer is c as -2 is -2/1 , -2/1 times 1/2 equals -1 which makes it so If x is -2 or less than it won’t exceed -1
