Answer:
1st question: BD=88
2nd question: AB=24
Step-by-step explanation:
1st question:
BD is the total length (7x-10) which is equal to BC+CD [(4x-29)+(5x-9)]
so we have:
7x-10=9x-38
28=2x
x=14
BC= 4*14-29=27
CD= 5*14-9=61
BD=88
2nd question:
Since BD=BC
5x-26=2x+1
3x=27
x=9
AC=BC+AB
BC=2*9+1=18+1=19
43=19+AB
AB=24
Answer:
Approximately 6.4
Step-by-step explanation:
We can use the pythagorean thereom here, that tells us (a^2)+(b^2)=c^2. C is the hypotenuse, the side opposite from the right angle, while a and b are the other sides. We can insert 5 and 4 as a and b, and solve for c
:(5^2)+(4^2)=c^2
:25+16=c^2
:41=c^2
:sqrt(41)=6.4=c (We square rooted both sides. 6.4 is only rounded to the nearest hundredths place.) Hope this helps!
There is no graph to figure this out...
