Answer:
y = - 
Step-by-step explanation:
Given
The denominator of the expression cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that y cannot be, that is
4y + 2 = 0 ( subtract 2 from both sides )
4y = - 2 ( divide both sides by 4 )
y = 
= - ← excluded value
Answer:
The correct answer is option a
Sin A = 2√13/13
Cos A = 3√13/13
Tan A = 2/3
Step-by-step explanation:
From the figure we can see that,a right angled triangle.
ΔABC
<u>To find side AB
</u>
AB = √(AC)² + (BC)² =√(36² - 24² )= √1872
AC = 12√13
<u> To find the trigonometric ratio
</u>
Sin A = BC/AB = 24/12√13 = 2√13/13
Cos A = AC/AB = 36/ 12√13 = 3√13/13
Tan A = BC/AC = 24/36 = 2/3
Answer:
=−m3n9+a3
Step-by-step explanation:
Let's simplify step-by-step.
a3−m3n9
=a3+−m3n9
Given -:
EF = 2X-7
FG = 4X-20
EG = 21
FIND OUT
EF =?
FG = ?
To proof
as given in the question
we have the value of EF = 2X-7 , FG = 4X-20 and EG = 21
Thus we have
EG = EF + FG
21 = 2X-7 + 4X- 20
21 = 6x - 27
48 = 6x
x = 8
Hence proved
Now put this value
Now
Hence proved
JKL is similar to PQR
so they want PR
JK
L is similar to
PQ
R
So PR is similar to JL
And they also give us the sides KL and QR
J
KL is similar to P
QR
Both of those sides are similar, so we can form a proportion.
Plug in the numbers:
Cross multiply:
Isolate PR
Simplify it
So your final answer is
