Same side interior angles are supplementary
[9tan(θ) * 9cot(θ)] / 9sec(θ)
First cancel out the 9's:
tan(θ)cot(θ)/sec(θ)
Recall the following trig identities:
tan = sin/cos
cot = cos/sin
sec = 1/cos
Thus, we can rewrite the expression as:
[ (Sin(θ)/cos(θ)) *(cos(θ)/sin(θ)) ] / (1/cos(θ))
In the numerator, the sine's and cosine's cancel each other out:
1 / (1/cos(θ))
which we can rewrite as cos(θ).
Answer:
the second one is true
Step-by-step explanation:
5=-4. 2nd one 5=5
83 divided by 9 equals 9.2222
9 multiplied by 9 equals 81
83 subtract 81 equals 2
there will be 2 left over
