Answer:
x = 3.7
Step-by-step explanation:
By applying sine ratio for the given angle B,
sin(39°) =
sin(39°) =
0.6293 =
AD = 4.41
By applying tangent ratio for the given angle C,
tan(50°) =
1.19 =
1.19 =
x = 3.7
Answer:
DE = 6 cm
Step-by-step explanation:
Let DE = x cm.
Since DE is parallel to AB therefore by the alternate interior angles theorem, m∠BAD = m∠ADE and m∠ABE = m∠DEB ............(1)
As AD is an angle bisector of ∠A, therefore m∠EAD = m∠DAB ; Since BE is an angle bisector of ∠B ⇒ m∠ABE = m∠EBD.
Therefore, from (1) We get , m∠EAD = m∠ADE and m∠EBD = m∠BED.
So, the triangles ADE and EDB are then isosceles with AE = ED and ED = DB.
So AE = DE = DB = x, and since the perimeter of ABDE is 30 cm, then
12 + x + x + x = 30
⇒ 12 + 3x = 30
⇒ x = 6
Hence, the length of DE is 6 cm.
The radius is always half of the diameter so it would be 20 inches
Answer:
A.)
Step-by-step explanation:
15 multiplied by 14 is the total number of women’s players.
14(m) is our unknown amount of men’s teams
Which has to be less than the amount of players who can register 476
