Answer:
the probablity of rolling a one is 1/6
Step-by-step explanation:
cos A is 0.8511 and tan B is 1.6
Step-by-step explanation:
Find the 3rd length or the hypotenuse.
<u>Pythagoras theorem</u>
=
+ 
=
+ 
= 64 + 25
hypotenuse = 
hypotenuse = 9.4
a) Cos A
<u>Data:</u>
Adjacent = 8
Hypotenuse = 9.4
<u>Formula:</u>
Cos (Angle) = 
Cos A = 
Cos A = 0.8511
A =
(0.8511)
A = 31.7°
b) Tan B
<u>Data: </u>
Opposite = 8
Adjacent = 5
<u>Formula:</u>
Tan (Angle) = 
Tan B = 
Tan B = 1.6
B =
(1.6)
B = 58°
Therefore, cos A is 0.8511 and tan B is 1.6.

Answer:
n+8 = 40
n=32
Step-by-step explanation:
Let the number be n
8 more than means
n+8
is equal to
n+8 =
n+8 = 40
We can solve this by subtracting 8 from each side
n+8-8=40-8
n = 32
The number is 32
3x+50 = 6x - 10
6x -3x = 50+10
3x = 60
x = 20
answer
x = 20
