Given:
There are given that the 25 ft ladder and angle is 70 degrees.
Step-by-step explanation:
To find the height of the building, first, we need to draw the image:
Then, the image will be:
Now,
From the above figure, we need to find the value of x.
So,
To find the value of x, we need to use the sin function.
Then,

Then,
![\begin{gathered} s\imaginaryI n70^{\operatorname{\circ}}=(AB)/(AC) \\ s\imaginaryI n70^{\operatorname{\circ}}=(x)/(25) \\ x=sin70^(\circ)*25 \\ x=23.5\text{ ft} \end{gathered}]()
Final answer:
Hence, the height of the building is 23.5 ft.
