Answer:
x/y = 88/7
Step-by-step explanation:
x+y=19
x+3y=12y+5
First rewrite second equation as:
x +3y-12y = 5
Combine like terms:
x-9y = 5
Now you have:
x+y=19
x-9y = 5
Elimination method Subtract 2 equations:
10y = 14 Divide both sides by 10
y = 14/10 = 7/5
Plug in y in any given equation and calculate x:
x+ 7/5 = 19 Subtract 7/5 from 19
x = 88/5 = 17 3/5
x/y = 88/5 : 7/5
Answer:
<em>75√2 </em>
Step-by-step explanation:
The triangle is isosceles right angled.
y² = 75² + 75² = 2(75²)
y = <em>75√2</em>
