I have no idea I am only in Middle School
So the formula is y=mx+b
the answer is y=-1x or -x+3 in cleaner form
y=-1x+3
Right triangle means we can use a^2+b^2=c^2
isosceles means 2 sides are equal legnths
the hypotenuse is normally the longest side so the equal sides are the other sides so therefore
a=b
therefor
(a^2)+(a^2)=c^2
2(a^2)=16^2
2(a^2)=256
divde both sides by 2
a^2=8
the side legnth of the other 2 sides is the square root of 8 which is aprox 2.8284271247452
but we only want the tenth so we look at the hundreths as well
2.82
round to the nearest tenth
2.8 cm is the answer of the legnths
I’m not sure about the first 2
The answer to your question is D
