You are tackling a trigonometry question here. I recommend remembering the functions and drawing the triangle out.

What is the value of x?<br> 12 units<br> 10<br> 15 units<br> 20 units<br> 24 units
vesna_86 [32]

Answer:

x = 20 units

Step-by-step explanation:

Using the Altitude- on- Hypotenuse theorem

( leg of Δ SRQ )² = (part of hypotenuse below it ) × ( whole hypotenuse ), so

x² = 16 × (16 + 9) = 16 × 25 = 400 (take the square root of both sides )

x = \sqrt{400} = 20

two trains leave stations 210 miles apart at the same time and travel tword each other. one train at 85 miles per hour while the
hodyreva [135]

recall your d = rt, distance = rate * time.


let's say we have two trains, A and B, A is going at 85 mph and B at 65 mph.


they are 210 miles apart and moving toward each other, at some point they will meet, when that happens, the faster train A has covered say d miles, and the slower B has covered then the slack from 210 and d, namely 210 - d.


When both trains meet, A has covered more miles than B because A is faster, however the time both have been moving, is the same, say t hours.


\bf \begin{array}{lcccl} &\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\ \cline{2-4}&\\ \textit{Train A}&d&85&t\\ \textit{Train B}&210-d&65&t \end{array}\\\\ \dotfill\\\\ \begin{cases} \boxed{d}=85t\\ 210-d=65t\\[-0.5em] \hrulefill\\ 210-\boxed{85t}=65t \end{cases} \\\\\\ 210=150t\implies \cfrac{210}{150}=t\implies \cfrac{7}{5}=t\implies \stackrel{\textit{one hour and 24 minutes}}{1\frac{2}{5}=t}

The above question is a mathematical proof of the relationship between Lines and angles related to a Rhombus. See the proof below.

<h3>What is a Rhombus?</h3>

A Rhombus is a parallelogram with four sides (that is a quadrilateral). It's sides however are all of equal length.

<h3>What is the above proof?</h3>

  • ∠DEC ≅ ∠BFC  Reason = All Right Angles with Equal dimensions are congruent.
  • ∠C ≅ ∠C  Reason = It is the same angle for the two Right angles above which are congruent, hence Reflexive Property.
  • Δ DEC ≅ Δ BFC  Reason = Angle Angle Side. The triangles are said to be congruent when two angles and a non-included side of one triangle match the corresponding angles and sides of another triangle.
  • \overline {DC}  ≅ \overline {BC}  Reason = The corresponding parts of congruent triangles are congruent. Also, it is a parallelogram with all congruent sides.
  • ABCD is a Rhombus Reason = Its sides are all congruent.
