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 = = 20
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.
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.
≅
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.
