Step-by-step explanation:
FV cos 43 = TV
FV (0.73135370161 ) = 53
FV = 72.468 = 72.47
Answer:
Wouldn’t the intercept be zero?
5x - 9 ≤ 21
5x ≤ 21 + 9
5x ≤ 30
x ≤ 30 ÷ 5
x ≤ 6
Answer:
D
Step-by-step explanation:
you take away 12 from the total and you'll find how many Zach read (20) then 12+20=32
Answer: 11.34
Step-by-Step Explanation:
We are given 2 Right Triangles. In the Triangles, as we see, AC = AD + DC.
So, we have to find the measure of AD and DC respectively using Pythagoras Theorem and then add both the measures to get AC.
In Triangle BAD,
AB = 7.5
BD = 6.5
AD = Unknown
Therefore,
AB^2 = BD^2 + AD^2
(7.5)^2 = (6.5)^2 + AD^2
56.25 = 42.25 + AD^2
AD^2 = 56.25 - 42.25
AD^2 = 14
=> AD = √14 = 3.74
In Triangle BDC,
BD = 6.5
BC = 10
DC = Unknown
Therefore,
BC^2 = BD^2 + DC^2
(10)^2 = (6.5)^2 + DC^2
100 = 42.25 + DC^2
DC^2 = 100 - 42.25
DC^2 = 57.75
=> DC = √57.75 = 7.6
Therefore,
AC = AD + DC
AC = 3.74 + 7.6
=> AC = 11.34
