From the trigonometry:
tan θ = (sin θ) / (cos θ)
cot θ = (cos θ) / (sin θ)
∴ tan θ + cot θ = (sin θ) / (cos θ) + (cos θ) / (sin θ)
= [ sin² θ + cos² θ]/( sin θ cos θ) = 1 /( sin θ cos θ )
note : sin² θ + cos² θ = 1
m and 125º are supplementary angles:
m + 125º = 180º
m = 180º <span>– 125º
</span>m = 5<span>5º <</span>——<span>— this is the answer.
I hope this helps. =)

Answer:
Step-by-step explanation:
from the picture:
QP = QR
and
QR = RS
so
PQ + RS = QS
Process efficiency is a measure of the ratio of process outputs to inputs.
