Answer:
3 degrees
Step-by-step explanation:
Recall that the sum of the interior angles of a triangle is always 180 degrees. Here two interior angles are shown [ 25x and (57 + x) ], and the third can be calculated [180 - 45x].
Summing these up, we get (25x) + (57 + x) + (180 - 45x), or -20 - 19x, which we set equal to 180:
(25x) + (57 + x) + (180 - 45x) = 180. Subtract 180 from both sides, obtaining:
25x + 57 + x - 45x = 0. Then 26x - 45x = -57, or x = 3.
Cancel -5y and 5x
leaving you with
8x=-18
2x=58
add
10x = 40
x= 4
substitute to find y
5y+2x=58
5y+8=58
5y=50
y=10
In my knowledge
x = 24²+7²
= 576+49= 625
x= sqroot of 625
x = 25 (By Pythagoras Theorem)
