Answer:
x = 6.40312423743 y=12.8062484748
Step-by-step explanation:
To find the value of x, you must use the Pythagorean Therom.
a^2+b^2=c^2
5^2+4^2=c^2
25+16=c^2
41=c^2
Then find the square root of 41 so x = 6.40312423743.
Then to find y you must substitute the value of x in and use the triangle formula: 1/2(b)(h).
1/2(4)(6.40312423743)
y=12.8062484748
