Answer: 15º and 50º
Explanation:
The angles in a triangle add up to 180. 
180 - 115 = 65
3x + 10x = 13x
13x = 65
x = 5
3x = 15
10x = 50
 
        
             
        
        
        
X=3
91 + x^2
91 + 3^2 
91 + 9
91 + 9 = 100
        
                    
             
        
        
        
The answer is B. Use distance formula...
 
 
        
        
        
1.
25%
.3 + .2 + .15 + .1 = .75
1.00 - .75 = .25
2. 
120 students
There are 400 total students
.3 * 400 = 120
4.
tennis-
.1 * 400 = 40 students prefer tennis
football-
.25 * 400 = 100 students prefer football
140 students like football/tennis
5. 
400 students
There are four quarters in a whole
.25% = 100
100 * 4 = 400
 
        
             
        
        
        
The difference from distance and displacement is <u>the direction</u>
<h3>Further explanation</h3>
Distance is a scalar quantity that indicates the length of the trajectory that is traveled by an object within a certain interval. Distance has no direction, only has magnitude
Can be simplified distance = total meters traveled
displacement is a vector quantity that shows changes in the position of objects in a certain interval of time. Displacement has magnitude and direction
Can be simplified displacement = distanced traveled from starting point to ending point
Some examples of distanced and displacement
1. first move: move 4 meters north
second move: move 2 meters south
Distanced: 6 meters
Displacement: 2 meters north
2. first move: move 2 meters east
second move: move 4 meters west
Distanced: 6 meters
Displacement: 2 meters west 
etc
