Answer:
B
Step-by-step explanation:
<u>This is a right triangle as shown by the right angle.</u>
- The side opposite the right angle is the hypotenuse, which is 9.
 - The side opposite angle A is 3.
 
So we have the opposite of A and the hypotenuse.
The trigonometric ratio that relates opposite side to hypotenuse is SINE.

Since, we need angle A, 
 is A, opposite side is 3, and hypotenuse is 9, we substitute:

<em>To solve for the angle, we use our calculator and find the inverse sin of 
 :</em>

<em>Rounding to nearest tenth of a degree:</em>

B is the right choice.
 
        
             
        
        
        
Answer:
16 3/10
Step-by-step explanation:
Think about what fraction become .3 when put into a calculator 
that's a 3 in the tenths place in the decimal system so the fraction would be 3/10. Then finally add on the 16 
*an aside if this is wrong it it is possible that they have rounded 1/3 to one decimal place. (1/3 is usually .33333 repeating)
 
        
                    
             
        
        
        
The rule to remember for this problem is: i^2 = -1
(4 + i)(1 - 5i)
4 - 20i + i - 5i^2
4 - 19i + 5
9 - 19i
