This should be the equation:
n + 4/3n + 5/3n = 90
        
             
        
        
        
Hey! since it’s a 5 sided shape it’s area will be 540° so you add up 108+100+90+120=418
the final angle is 122*
then since angles on a straight line is 180° you minus 122 from 180 and x= 58°
        
             
        
        
        
Answer:
168
Step-by-step explanation:

Answer:
<h2>The answer is option A</h2>
Step-by-step explanation:
Since the triangle is a right angled triangle we can use the Pythagoras theorem to find the missing side
Using the Pythagoras theorem
That's

From the question 
x is the hypotenuse or the longest side of the triangle
Substituting the values into the above formula we have



Find the square root of both sides 
We have the final answer as
<h3>x = √130 m</h3>
