Option D:
Solution:
Given data:
Let the unknown degree be x.
To find the degree x:
Cancel the common factor 7 in the numerator and denominator.
Using trigonometry basic formula,
we know that .
So, x = 60°.
The unknown degree measure is 60°.
Hence option D is the correct answer.
Answer:
13) C (a, a) Y (a, 0)
14) B (0, b) P (a, 0)
Step-by-step explanation:
13) Y lies on x axis so it is Y(a,0)
ZY = YC = a
so for C coordinates are (ZY,YC) = (a, a)
14) B lies on y axis so it is B(0, b)
BK = BP = = distance between two points
so P is (a, 0) as it is same distance and on positive side of x axis
