Answer:
Step-by-step explanation:
AD =BC = FG = EH = 3
AB = DC = EF =HG = 4
BF =AE = DH = CG = 12
Use Pythagorean theorem,
Hypotenuse² = base² +altitude²
BD² = DC² + BC²
= 4² + 3²
= 16 + 9 = 25
BD = √25
BD = 5
DG² = DC² + CG²
= 4² + 12²
= 16 + 144
= 160
FD² = DG² + FG²
= 160 + 3²
= 160 + 9
= 169
FD = √169 = 13
FD = 13
Answer:
a) BD = 5
b) FD = 13
Step-by-step explanation:
For both questions we follow pythagoras therom.
For the first one we do 3^2 +4^2 = 25 and then we root this answer to 5
For the second we have to find the base of GD in order to find FD. GD will be 4^2+12^2 which equals to 160 and then you root.
Finally, we can find FD which is sqaure root of 160^2 + 3^2 = 169. The square root of 169 is 13. Answer is 13.

Step-by-step explanation:
b b b
Step-by-step explanation:
Y= x - 2. Y = 3x + 5
Putting value of y
x - 2 = 3x + 5
-2 - 5 = 3x - x
-7 = 2x
-7/2 = x
Putting value of x
Y = 3(-7/2) + 5
Y = - 10.5 + 5
Y = - 5.5
The most appropriate answer is C !!
