Sin 64= .898
sin 50= .766
sin 60= .913
(15)(.898)=13.47
Answer:
there is a 50/100 that it would land on zero heads or 1/2 chance
Step-by-step explanation:
Answer:
3x^4 + 7x^3 - 5x^2 + 8x - 13
Step-by-step explanation:
(3x^4 + 7x^3 - 9) - (5x^2 - 8x + 4) =
The negative sign to the left of the second set of parentheses changes every sign inside the parentheses.
The first set of parentheses is unnecessary, so we just drop it.
= 3x^4 + 7x^3 - 9 - 5x^2 + 8x - 4
Now we combine like terms.
= 3x^4 + 7x^3 - 5x^2 + 8x - 13
The measure of ∠DBC is 36°
In the circle, BD is the diameter and BC is the minor chord on the circle, due to which ∠BCD = 90°, in triangle BDC
Then,
Given arc BD measure is 54° i.e ∠BDC is 54°
The, from property of triangle, sum of all angles is 180°, we can find the third angle i.e. ∠DBC.
Thus, ∠DBC = 180°- 90°- 54°
∠DBC = 36°
