The answer to the question
Answer:
A
Ratio is 2:1
Step-by-step explanation:
Answer: A
Step-by-step explanation:
26+51+103=180(sum of internal angle of triangle)
Since it is under 985,000, you would round it down. So your answer rounded to the nearest ten thousand would be 980,000
The correct answer is B.
Determine and recall first the trigonometric functions:
Sin A = Opposite/Hypotenuse
Cos A = Adjacent/Hypotenuse
Tangent = Opposite/Adjacent
If for example we try to take an angle, for example the Y, then Y is opposite Y. The Hypotenuse will be the longer side which is going to denoted by X and the next side will be Adjacent which will be denoted by Z.
Use this test to answer:
Sin Y = Y/X
where:
Y = opposite
X = hypotenuse
Cos (90 - y) = cos (90 - 50) = cos 40
where Z = 40
we look for cos Z = Y/X
Therefore,
Sin Y = Cos (90 - Y)
