Answer:
(20+5)×10
Step-by-step explanation:
Pemdas said that brackets is first
so 20+5 is solved first
then it's multiplication or devision in this case multiplication is here
20+5=25
25×10=250
Answer:
Option B. MN/MO
Step-by-step explanation:
In a right angle triangle cosine of any acute angle = Base/ Hypotenuse
In the ∠ NMO Hypotenuse is MO and base of the triangle is MN.
Therefore cos (M) = Base / Hypotenuse = MN / MO
Therefore option B is the right answer.
29% would be the answer if you are rounding up
Answer:
To prove that ( sin θ cos θ = cot θ ) is not a trigonometric identity.
Assume θ with a value and substitute with it.
Let θ = 45°
So, L.H.S = sin θ cos θ = sin 45° cos 45° = (1/√2) * (1/√2) = 1/2
R.H.S = cot θ = cot 45 = 1
So, L.H.S ≠ R.H.S
So, sin θ cos θ = cot θ is not a trigonometric identity.
Answer:
they are not similar. their one angle is only equal
