Yes, it is true. Divide them and you get 12/30=.4 and 20/50=.4.
Answer:
The correct option is second one i.e 24 units.
Therefore the height of the triangle is

Step-by-step explanation:
Given:
An equilateral triangle has all sides equal.
ΔMNO is an Equilateral Triangle with sides measuring,

NR is perpendicular bisector to MO such that
.NR ⊥ Bisector.
To Find:
Height of the triangle = NR = ?
Solution :
Now we have a right angled triangle NRM at ∠R =90°,
So by applying Pythagoras theorem we get

Substituting the values we get

Therefore the height of the triangle is

Answer:
A
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = D(- 4, - 3) and (x₂, y₂ ) = E(- 5, 3)
d = 
= 
= 
=
≈ 6.1 → A

Step-by-step explanation:
Answer:
Both Tom and Jerry will apart 176 miles in 2 hours .
Step-by-step explanation:
Given as:
Tom and Jerry moves in opposite direction
The speed of Tom = 38 mph
The speed of Jerry = 50 mph
Let The distance cover by Tom = x mile
The distance cover by Tom = ( 176 - x ) miles
Time taken by both are same = T hour

Or, Time taken by Tom
T =
... 1
∴ x = 38 T
And Time taken by Jerry

Or, T =
So , put the value of T from 1
=
Or, 50 × x = ( 176 - x ) × 38
So 50 x + 38 x = 6688
Or, 88 x = 6688
∴ x =
= 76 mile
So, From, eq 1
T =
or, T =
= 2 hours
Hence both Tom and Jerry will apart 176 miles in 2 hours . Answer
