Answer:
38.7°
Step-by-step explanation:
We can solve the triangle using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where
SOA stands for 
Sin Ф = opposite side/hypotenuses side
CAH stands for 
Cosine Ф = adjacent side/hypotenuses side
TOA stands for 
Tangent Ф = opposite side/adjacent side
The hypotenuse is the side facing the right angle while the opposite is the side facing the given angle.
Considering the triangle with respect to angle x, 8cm is the opposite side, 10cm is the adjacent side
hence
Tan x = 8/10
Tan x = 0.8
x = tan -1 0.8
= 38.7°
 
        
             
        
        
        
Answer:
1600
Step-by-step explanation:
1.25x + 1000 = 3000
Subtract 1000 from both sides
1.25x = 2000
Divide both sides by 1.25
x = 1600
 
        
             
        
        
        
I believe your answer is 8.
Three times a number less than twice the number and nine is seventeen can be written as: 3n - 2n + 9 = 17
Solve for n as follows:
3n - 2n = n 
n + 9 = 17
17 - 9 = 8
Hope this helps! :)

Answer:
See below.
Step-by-step explanation:
There are 2 options in finding the difference between f and 35, as you did not state in the question which if the 2 is the larger number.
(f-35)-5=f-35-5
 =f-40
OR
(35-f)-5=35-f-5
 =30-f
