Answer:
21.8 m
Step-by-step explanation:
The tangent function relates this angle, height and horizontal distance:
height
tan 23.6 degrees = --------------
50 m
Then the height of the building is (50 m)(tan 23.6 degrees) = 21.8 m
Answer:
Enough water has been poured .
Step-by-step explanation:
The garden needed water in a week = 5 liters
Jacob poured water on Monday = 326 ml = ( 326/ 1000) liters = 0.326 liters.
SEAN poured water on Tuesday = 1.5 liters
Gavin poured water on Wednesday = 2312 ml = ( 2312/ 1000) = 2.312 liters.
Stephen poured water on Thursday = 894 ml = ( 894/ 1000) = 0.894 liters
The total amount of water poured by all these people = 0.326 + 1.5 +2.312 +0. 894 = 5.032 liters
Here we can see that water has been poured is more than the water required in a week.
B. y=12x+7
Explanation
The slope is 12; slope=m
The yint is 7; yint=b
The equation of a line is set up as so
y=mx+b
Now we just need to replace the variables with the numbers
y=12x+7
Answer:
Well the Peloponnesian War helped by the war being so grand and so many people died that the armies were weakened and that led to Macedonia (Phillip II and Alexander the Great) to overrule all of Greece.
I hope that helped
