Answer: The answer to your question is 6
Step-by-step explanation:
To solve this problem we will use proportions. We will compare the largest right triangle and the medium size triangle.
                           Medium triangle                     Large triangle
hypotenuse                 y                                            9 + 3
adjacent size               9                                               y
- Write the proportions
                                   y/9 = (9 + 3)/y
-Solve for y
                                   y² = 9(12)
                                   y² = 108
                                   y =   
-Find the prime factors of 108
                                   108  2
 54 2
                                      27 3
                                       9  3
                                       3   3
                                        1
then,       108 = 2² 3³
-Expressthe root as fractional exponents
                                   2²/² 3²/² 3¹/²
-Simplification
                                    2(3)(3)¹/²
-Result
                                       6
 
        
             
        
        
        
Answer:
∠A= 80°
Step-by-step explanation:
if they are supplementary then put them equal to 180
7x + 3 +7x + 23 = 180
14x + 26 = 180
14x = 154
x= 11
now plug in
7(11)+3
77+3= 80
 
        
             
        
        
        
Answer:
The Susana swam the fastest.
Step-by-step explanation:
<u>Speed</u> : It is defined as the distance traveled per unit time.
<u>Formula used</u> : 
First we have to determine speed of the following persons.
<u>For Tawni :</u>
Distance = 50 m
Time = 40.8 s
1.225 m/s which is the speed of Tawni.
--
<u>For Pepita :</u>
Distance = 100 m
Time = 60.2 s
1.661 m/s which is the speed of Pepita
--
<u>For Susana :</u>
Distance = 200 m
Time = 112.4 s
1.779 m/s which is the speed of Susana
From this we conclude that, in this problem meter affects the response and the speed of Susana is more than the Pepita and Tawani.
Thus, Susana swam the fastest.
 
        
             
        
        
        
I think it is -2, if that helps
        
             
        
        
        
The answer should be 24, because you can mark out 5,and 10 cuz it doesn’t make since
