Answer:
(3, 2)
Step-by-step explanation:
I will solve using the elimination method
x + y = 5
- (x - y = 1)
---------------
2y = 4
y = 2
plug y = 2 into any equation and solve for x
x + 2 = 5
x = 3
(3, 2)
From the law of sines, we have
where 
is the leg we're interested in, 
is the hypothenuse, 
is the angle opposite to , and 
is the angle between and .
So, in the first case, we can use
And in the second excercise, we use
Answer:a²=b²+c² in a right angle triangle so answer is root 136
Step-by-step explanation:
The answer is 30.
You need to use sine here
So:
