ΔXYZ was reflected to form ΔLMN.
1 answer:
For the given figure , Option A , B ,C , F will be true.
<h3>What is a Triangle ?</h3>A triangle is a polygon with three sides , angles and vertices.
It is given that
Triangle X Y Z is reflected to from triangle L M N.
The diagram is attached with the answer.
As the Triangle is reflected , The shape of the image doesn't change and also
From the diagram it can be concluded that
ΔXYZ ≅ ΔLMN
and as the triangles are Congruent , By CPCTC
∠Y ≅ ∠M
∠X ≅ ∠L
XZ ≅ LN
Therefore , Option A , B ,C , F are the options that are true for the given figure.
The missing figure is attached with the answer.

Option B is correct.
67.5 degree
Step-by-step explanation:
To find the angle between the hands of a clock.
Given that:
Hands of a clock at 5 : 15.
We know that:
A clock is a circle and it always contains 360 degree.
Since, there are 60 minutes on a clock.
so, each minute is 6 degree.
The minutes hand on the clock will point at 15 minute,
then, its position on the clock is:
Also, there are 12 hours on the clock
⇒Each hour is 30 degree.
Now, can calculate where the hour hand at 5:00 clock.
⇒
Since, the hours hand is between 5 and 6 and we are looking for 5:15 then :
15 minutes is equal to of an hour
⇒
Then the angle between two hands of clock:
⇒
Therefore, the angle between the hands of a clock at 5: 15 is: 67.5 degree.
Answer:
yes
Step-by-step explanation:
because area of sphere equals =
so if we doubled the radius the surface area will be doubled
Answer:
Step-by-step explanation:
We want to write the trignometric expression:
As an algebraic equation.
First, we can focus on the inner expression. Let θ equal the expression:
Take the secant of both sides:
Since secant is the ratio of the hypotenuse side to the adjacent side, this means that the opposite side is:
By substitutition:
Using an double-angle identity:
We know that the opposite side is √(u² -100), the adjacent side is 10, and the hypotenuse is u. Therefore:
Simplify. Therefore:
