Sin60=DF/FE
Root 3/2= DF/ 18 Root 3
DF= 18*3/2
DF= 27 units
cos60=DE/FE
1/2=DE/18 Root 3
DE= 18 Root 3/2
DE= 9 Root 3 units
Answer:
h = (m/4 - as)/s
Step-by-step explanation:
s = m / 4(a+h)
(a+h) · s = m/4 ><em>multiplied </em><em>(a+h)</em><em> on both side</em>
as + hs = m/4 ><em>distributed the </em><em>s</em><em> to </em><em>(a+h)</em>
hs = m/4 - as ><em>subtracted </em><em>as</em><em> on both side</em>
h = (m/4 - as)/s<em> >divided </em><em>s</em><em> on both side</em>

Answer:
3,989.2
Step-by-step explanation:
The word tenth goes after the decimal so the number is 2 and sense the number 3 is after and will be rounded down the answer is 3,989.2
Answer:
It would be triangles A & C
Step-by-step explanation:
This is because all of the angles within triangle add up to 180, with this, you can do the following to find the missing sides:
Tri A:
180-110-30 = 40
Tri B:
180-45-30 = 105
Tri C:
180-110-40 = 30
When you do this, look at the angles of the triangles. You see that Triangle A with the angles 110, 30, and 40 all match with those seen in Triangle C.
Therefore, the two triangles are congruent.
