You would use pythagorean's theorem which is
a^2 + b^2 = c^2
a= height of the building
b= length of the shadow
c= length from the tip building to the shadow
now plug them in!
a^2+ 28^2 = 34^2
a^2 + 784 = 1156
substract 784 from both sides
a^2 = 362
square root both sides
a = the square root of 362 which is 19.5 m
Step-by-step explanation:
7x-3y=21 to find x int.
7x-3×0=21
7x/7=21/7
x=3 and to find y int.
7x-3y=21
7×0-3y=21
-3y/-3=21/-3
y=-7
so x int. is 3 and y int.is -7
Answer:
14.25L
Step-by-step explanation:
3(1.25) + 3(2.5) + 3(1) = 14.25L

You know that the radical is in the simplest expression form if there are not squares or cubed roots in the radical. If there is then it can be simplified more. When the radical can no longer be simplified then it is in the simplest form
