EF and FG are equal so EF would be 6.1
6.1+6.1=12.2
EG=12.2
I think it is 63 because a triangle equals 180
Answer:
150 + 150 = 300
Step-by-step explanation:
50x = 30y
x + y = 8
~~~~~~~~~~~~~~~
x = 8 - y
50(8-y) = 30y
400 - 50y = 30y
400 = 80y
y = 5
x= 3
8 is the hypotenuse and x is the adjacent side to the 60-degree angle. This means that you would need cosine (adjacent over hypotenuse) or secant (hypotenuse over adjacent). Cosine is not an option so it's secant.
sec 60 degrees = 8/x
Next, in a 30 60 90 triangle, you know that the side lengths are 1, 1/2 and sqrt(3)/2. So the secant of 60 degrees is 1 divided by 1/2 which is 2.
So the answer is the first question: x = 4
The answer to this is y <= -8.
