Answer:
X = 8 And y = 1/5
Step-by-step explanation:
add equaction i and education ii,
2 -5y = 1
2x +5y = 17
------------------
2+2x = 18
or, 2x = 18 - 2
or X = 16/2
or X = 8
Again from equation i,
2 - 5y = 1
or, -5y = 1 - 2
or, -5y = -1
or, y = -1/-5 (cut the subtraction sign)
or, y = 1/5

Step-by-step explanation:
In order to find the answer we need to use the following formula:
where:
a, b, c are the length of the sides and 
the angle, so:
In conclusion, 
, so the answer is B.
Answer:
The converse of Pythagorean Theorem states:
<em>If the square length of the longes side of a triangle is equal to the sum of the squares of the other two sides, then it's a right triangle.</em>
<em />
We use the converse of Pythagorean Theorem to prove that a triangle is a right triangle. It's like the inverse use of the theorem. Often, this theorem is used to find the length of a side of a triangle when we already know it's a right triangle. However, when we don't know that is a right triangle, we use the converse to prove it.
A: 2 units wide, 3 units long, 8 units tall.
C: 4 units wide, 6 units long, 3 units tall.
Hope this helps!
