tan 52 = 180/a; a = 180/tan 52
tan 43 = 180/b; b = 180/tan 43
you need to calculate, a-b = 180/tan 52 - 180/tan 43
substitute the value of tan thetas, and calculate it simply...
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Let x represent the initial weight of Porky the pig. 
Porky the pig weighs 1,125 lbs less than Kobe the Cow. This means that the initial weight of Kobe the cow is 
x + 1125
After each gains 50lbs. Kobe the Cow will weigh ten times as much as porky the pig. This means that 
(x + 1125) + 50 = 10(x + 50)
x + 1125 + 50 = 10x + 500
10x - x = 1125 + 50 - 500
9x = 675
x = 675/9
x = 75
Porky's current weight is 
75 + 50 = 125 lbs
Kobe's current weight is 
(75 + 1125) + 50 
= 1250 lbs
 
        
             
        
        
        
Answer:
If you've learnt sin(A+B) = sinAcosB + cosAsinB,
sin(4u)
= sin(2u+2u)
= sin(2u)cos(2u) + cos(2u)sin(2u)
= 2 sin(2u) cos(2u).
 
        
             
        
        
        
Answer:
1. All student who attend the school.

The population here is consists of all student who attend the school because administrators wants to assess about opinion of students about course offering of school and all possible observational units in this survey are all the students who attend the school.
 
        
             
        
        
        
Answer:
I like saying rise over run because it helps me remember that rise means how many units you move up or down from point to point which on a graph would be a change in the y values. Also that run means how far left or right you move from point to point which on the graph would mean a change of x values.
