No the don't add up to one eighty I'm pretty sure if not tell me
Answer:
1) The value of x= 0.0642
2) 




Step-by-step explanation:
1) Given : A right angle triangle with sides x and 10 and angle is 50°
To find : Value of x
Solution : Since, it is a right angle triangle
Therefore, we apply 
Where Base = x, Hypotenuse= 10, angle = 50°



The value of x= 0.0642
2) Given : 
To find : Value of 
Solution : We have given 

so, B= 7 , H=25
By Pythagoras theorem,





Now, P=24, B=7, H=25





I'm not sure! Let me think about it, and if I get something then I will let you know!!! ;D
6(w) = v
6(3) = 18
I think, hope I helped :)
