Answer:
Step-by-step explanation:
a, -14
Answer:
171.65
Step-by-step explanation:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving forA
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=5·10+5·10+5·10+1
2·﹣54+2·(5·5)2+2·(5·5)2﹣54+2·(5·5)2﹣54≈171.65064
Uh is there a picture cuz we can't know what's a vetex angle if we don't see a pic
Answer:
the answer would be 11.62
Step-by-step explanation:
16^2 -11^2= 11.62^2
The quadratic formula is
and in the equation ax^2+bx+c=0
so now all you have to do is substitute the numbers into the quadratic formula
