Answer: We can't see the ratios.
Step-by-step explanation:
all angles = 180 degrees total
add the ratios: 2 +4 +9 = 15
180/ 15 = 12
12*2 = 24
12*4 = 48
12*9 = 108
108 + 48 + 24 = 180
the three angles are: 24, 48 and 108

Answer:

Step-by-step explanation:
Given that,
...(1)
We need to find the value of x.
We know that,
sin30 = 1/2
Use it in equation (1).

So, the value of x is equal to
.
Y - 4 = -8/7(x - 4)
the answer to the question is d
