Answer:
The Value of
.
Step-by-step explanation:
We have Named the figure please find the attachment for your reference.
Given:
PR = y
QR = a
RS = b
PS = z
PQ = x
QS = 15
∠P = 90°
∠R = 90°
∠Q = 60°
∠S = 30°
We need to find the Value of 'a'.
Solution:
Now we know that:
In Δ PQS
∠P = 90°
∠S = 30°
Now we know that;


Substituting the given values we get;

Now we know that;

So we can say that;

Now In Triangle PQR.
∠R = 90°
∠Q = 60°
So we can say that;


Substituting the given values we get;

Now we know that;


So substituting the values we get;

By Using Cross Multiplication we get;

Hence The Value of
.
