Answer: 47.86
Step-by-step explanation:
tan x =42/38
tan x= 1.105
x= 47.86
The hundredth is the second decimal place. You know the rounding rules are where you look at the previous place and if it's 5 or above the number place your rounding to goes up. So the answer is 423.41
Dividing both sides by-3
the division sign will still be the same
your answer is c>2
The roots of x^{2} 6x-55=0 the answer is going to be
the roots is going to 3[1980/6}
x= 2.09284539
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
