Answer:
12.7
Step-by-step explanation:
12.7
Basically u are gonna wanna use pythagoras first
BC = √(12^2 - 6^2) = √(144 - 36) = √(108) = 10.39230485
Also the Side Angle Side rule comes into play use the following
BC/sin(55) = CD/sin(90) <----- angle
BC/sin(55) = CD/sin(90)
sin(90)BC/sin(55) = CD
1*BC/sin(55) = CD
BC/sin(55) = CD
10.39230485/0.819152044 = CD
12.68666167 = CD
12.7 = CD
Step-by-step explanation:
A tenth is 0.1
To round of to the nearest tenth means to round it of to 1 decimal place.
Now, look at the number after the tenth place with is 0.03 or simply 3.
If the digit is 0-4, you round the whole number down.
Hence, 15.839 is 15.8 to the nearest tenth digit.
If the tenth digit is 5-9 such as 15.85 or 15.87, you round the number up, to give 15.9
Answer:
0.6
Step-by-step explanation:
12/20 = 6/10 = 0.6
P: x + 2 = 9
x = 7 # Subtract 2 from both sides
E: q - 5 = 12
q = 17 # Add 5 to both sides
H: 6 + m = 27
m = 21 # Subtract 6 from both sides
Y: t - 14 = -3
t = 11 # Add 14 to both sides
J: u - 7.5 = 2.4
u = 9.9 # Add 7.5 to both sides
I: n + 7 = -20
n = -27 # Subtract 7 to both sides
G: d - 1 = -16
d = -15 # Add 1 to both sides
A: b - 40 = -25
b = 15 # Add 40 to both sides
M: 18 + w = 7
w = -11 # Subtract 18 from both sides
L: k + 8.3
k = 11.5 # Subtract 8.3 from both sides.
13.75 inches, just get a calculator and type in 1,100/80 and you'll get your answer.
