Actually Welcome to the concept of Pythagorus theorem,
here, the perpendicular height = 24 ft and the base = 10ft ,
hence then length of the ladder is the Hypotenuse.
so we get as,



hence, l = 26 ft
so the length of the ladder is 26 feets.
Answer:
33
Step-by-step explanation:
Supplementary angles add up to 180 degrees. So, 4x + (x+15) = 180
5x+15=180
5x=165
x=33
Chance coins have a greater mass because the coin mass of a quarter is 5.67 you multiply by 8, which is the number of quaters you have and you get 45.36 grams. if you do the same with the dollar coins, meaning you multiply the the mass by the number of coins, you should get 40.5 grams.
To find the volume, you do area multiplied by thickness( or height)
In this example, you do (1/2*9*6)*10 which is 270
hope I helped ;)
