Answer: The angle of depression is 51.34°.

Step-by-step explanation:

1. You can make the diagram shown in the figure attached. Where $A$ is the point where the clue is and $B$ is the point where Tyler is.

2. To calculate the angle of depression, which is identified in the diagram as $\alpha$ , you can use $tan^{-1}$ , as following:

$tan^{-1}(\alpha)=\frac{3.5}{2.8}$

3. Then, you obtain the following angle of depression from the clue to the point where Tyler is:

$\alpha=51.34$ °

Nice summary problem.

<AEC

AEC = 360 - 243.5 = 116.5
The number of degrees in 1 rotation of a circle = 360o. You have accounted for 243.5 degrees. What is left over is the answer.

<EAD and <ECD

Both of these are tangents to a circle. Tangents meet radii at 90 degree angles.

<EAD = <ECD = 90 degrees

<ABC

<ABC is 1/2 the central angle. The Central angle is <AEC

< AEC = 116.5
<ABC = 1/2 * 116.5
<ABC = 58.25

<ADC

There are 2 ways of doing this. You should know both of them.

One

All quadrilaterals = 360 degrees. You know three of the angles. You should be able to find ADC

<ADC + 90 + 90 + 116.5 = 360 Add the four angles together.
<ADC + 296.5 = 360 Combine terms on the left
<ADC = 360 - 296.5 Subtract 238.25 from both sides
<ADC = 63.5 Answer

Method Two

<ADC = 1/2 (major Arc - Minor Arc) This formula is fundamental to circle / tangent properties. The Major arc is the larger of the two parts of the circumference of a circle. The Minor arc is the smaller.

<ADC = 1/2(243.5 - 116.5)
<ADC = 1/2(127)
<ADC = 63.5

A line passes through the point (-7, 5) and has a sloe of 1/2. Which is another point that the line passes through?

Mekhanik [1.2K]

The point through which the same line is passing will be (9,13) so option (C) will be correct.

<h3>What is a line segment?</h3>

A line section that can connect two places is referred to as a segment.

A line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

The equation of any line with slope m can be given as

y = mx + c

Given,

slope m = 1/2

Point of passing (-7, 5)

So,

5 = -7/2 + c ⇒ c = 17/2

So the equation will be,

y = x/2 + 17/2

2y = x + 17

Now checking all points (9,13) is satisfying.

2(13) = 9 + 17

26 = 26

Hence point (9,13) is passing through the line.

Plz help me with my geometry asap 50 pts and brainliest NO SCAMMING OR I WILL REPORT

bearhunter [10]

Step-by-step explanation:

1. You already got the first step, where D is the midpoint of AC and AB is congruent to BC, since it's given.

2. AD will be congruent to DC, via the definition of a midpoint (a midpoint is the middle point of a line segment, and it splits the segment into two congruent parts)

3. BD is equal to BD, via reflexive property. ( It's a shared side between the two triangles)

4. that means that ΔADB ≅ΔCDB via SSS rule.

5. ∠ABD ≅∠CDB by CPCTC (corresponding parts of congruent triangles are congruent)

Hope this helps! :)
