Answer:
Step-by-step explanation:
Let a be the length of the altitude, then from the given triangles, applying the basic proportionality theorem, we get
⇒
⇒
⇒
⇒
Thus, the length of altitude is: 12 cm.
Now, 
⇒
⇒
Also, 
⇒
⇒
Thus, the lengths of the legs of this triangle are 14.83 and 20 cm.
Answer:
Step-by-step explanation:
So we have:
This is the same as:
Separate:
Replace the second term with i:
The square root of 66 cannot be simplified.
So, this is our answer :)
The halves of the rhombus separated by line BD are equilateral triangles.
∠BAD = 60°
so
∠ADM is 0.80*60° = 48°.
∠BMD is an exterior angle to ΔAMD, so is equal to the sum
∠BMD = ∠BAD + ∠ADM
= 60° +48° = 108°
∠BMD = 108°
1 mile=1258 foot
1 foot=12 inches
63360 is the correct answer
Circumference formula is πd
C = (3.14)(34)
C = 106.76
Hope this helps :)
