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°
Answer:
The distance between points 8 and -5 is 13
Step-by-step explanation:
We need to find distance between points 8 and -5
The formula used to find the distance is:
Absolute value is used to get only positive values. i.e |-1|=1 if required.
We are given: b=8 and a=-5
Putting values and finding distance
So, the distance between points 8 and -5 is 13
Answer:
Step-by-step explanation:
Given
initial Velocity(u)=44 ft/s
ball initial height =4 ft
as launch angle is not given so considering ball is hit vertically upward
where u =initial velocity
v=final velocity
a=acceleration
s=distance traveled
time taken to reach 30.06 ft
total distance to reach ground=4+30.06 ft=34.06 ft
t=1.45 s
Answer:
125
Step-by-step explanation:
0+1+9, 0+2+8, 0+3+7, 0+4+6, 0+5+5 gives 27 ways including permutations.
1+1+8, 1+2+7, 1+3+6, 1+4+5 gives 21 ways.
2+2+6, 2+3+5, 2+4+4 gives 12 ways
3+3+4 gives 3 ways
With permutations this gives 27+21+12+3=63 ways.
