What basic trigonometric identity would you use to verify that cscx secx cotx=csc^2x

Solution:

We are given an trigonometry expression and to prove it using trigonometry identity.

Trigonometry Identity,

Taking Left hand side,

Cancel like terms from numerator and denominator

Hence Proved  

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
