458= 339+34h
Subtract 339 from both sides
119=34h
Divide both sides by 34
3.5=h
Final answer: 3 and a half hours
Answer:
x=30
Step-by-step explanation:
So we know that a shape with 4 angles equal 360 degrees and this has 4 angles. Since we know that 4x is one and 2x is one We cna use the vertical angles to find the other two. Since 4x is opposite of an unknown side it is also 4x becuase vertical angles are equal becuase they are opposite sides of each other. Same thing with 2x
Now add them all up
4x+4x+2x+2x which will equal 12x
now 12x=360
x=30
Use formula a squared equals to c squared minus b squared
40^2-24^2 is 1024
Square root of 1024 is 32.0
