LHS: cos^2 A( 1+cot^2A)
=cos^2A(cosec^2A) ,1+cot^2A=cosec^2A
=cos^2A( 1/sin^2A)
=(cos^2A/ sin^2A)
=cot^2A
=RHS
Hope this can help.
Answer:
a) X would be marked 2 cm away from point A towards the point B
b) X would be marked 1.5 cm away from point P towards the point Q
Step-by-step explanation:
Data provided in the question:
Length of AB = 6 cm
Length of PQ = 6 cm
a) AX : AB 1 : 3
This means

on substituting the value of AB, we get

or
AX = 
or
AX = 2 cm
Hence,
X would be marked 2 cm away from point A towards the point B
b) PX: XQ 1 :3
This means

or
⇒ 3PX = XQ .............(1)
also,
PX + XQ = PQ
or
PX + XQ = 6 cm
substituting the value of XQ from (1)
PX + 3PX = 6 cm
or
4PX = 6 cm
or
PX = 
or
PX = 1.5 cm
Hence,
X would be marked 1.5 cm away from point P towards the point Q

Answer:
D) radical 26
Step-by-step explanation:
So this is a question where you need to find the hypotenuse of a triangle
the sides are 1 and 5
you can use Pythagoras (a^2+b^2=c^2)
substitute the values in
1^2+5^2=c^2
simplify the exponents
1+25=c^2
add them together
26=c^2
take the square root of 26
the answer is radical 26
