45/2 or 22 1/2
------------------
To do this problem you need to find angle adc which is a part of angle BDA. angle BDA is 90 degrees so the 2 parts must add up to 90 degrees so you set up the problem like this
-2x + 144 - 3x +51 =90
then you combine like terms
-5x +195 = 90
then you subtract 195 from 90
-5x = -105
then you divide -5 by -5 and -105 by -5 and get
x=21
then you plug x in and get your angle measure
-3(21) +51
then you get the angle measure as 114 degrees.
Answer:
D. 7/8
Step-by-step explanation:
They are increasing the numerator and denominator by one each time the sequence continues.
Answer:
BE = 2
Step-by-step explanation:
2(BE) = AC
2(3x - 7) = 8x - 20
6x - 14 = 8x - 20
6 = 2x
x = 3
BE = 3(3) - 7 = 2
Answer:
Step-by-step explanation:
Time of flight of projectile
The time it takes from an object to be projected and land is called the time of flight. It depends on the initial velocity of the projectile and the angle of projection. The maximum height of the projectile is when the projectile reaches zero vertical velocity.
