Step-by-step explanation:
The triangle is a right angle triangle. This is because one of its angles is 90 degrees.
Let us determine x
Taking 47 degrees as the reference angle,
x = adjacent side
11 = hypotenuse
Applying trigonometric ratio,
Cos # = adjacent side / hypotenuse
# = 47 degrees
Cos 47 = x/11
x = 11cos47
x = 11 × 0.6820
x = 7.502
Let us determine y
Taking 47 degrees as the reference angle,
y = opposite side
11 = hypotenuse
Applying trigonometric ratio,
Sin # = opposite side / hypotenuse
# = 47 degrees
Sin 47 = y/11
x = 11Sin47
x = 11 × 0.7314
x = 8.0454
Answer:
4. 7/100
5. -3 85/99
6. 26/33
7. 2 27/50
Step-by-step explanation:
4.
0.07 = 7/100
5.
We need to change 0.8585... into a fraction.
100x = 85.8585...
(-) x = 0.8585...
-----------------------------
99x = 85
x = 85/99
-3.858585... = -3 85/99
6.
100x = 78.7878...
(-) x = 0.7878...
------------------------------
99x = 78
x = 78/99
x = 26/33
0.787878... = 26/33
7.
2.54 = 2 + 0.54 = 2 + 54/100 = 2 + 27/50 = 2 27/50
'a' is the correct answer
