A carpenter leans an extension ladder against a house to reach the bottom of a window 30 feet

above the ground. As shown in the diagram below, the ladder makes a 70° angle with the ground.

To the nearest foot, determine and state the length of the ladder.

Answer:The answer will be 35ft

Step-by-step explanation:

One way that you can answer this is by using sin law. You will put the length of a side on top and the corresponding angle that faces towards that side at the bottom of a fraction. So for this one it will be 30/sin (70) = x/sin (90) The 90 comes from the bottom of the building with the ground. And the side the angle faces is the ladder. After that you put 30sin (90) / sin (70) to find x. And you get 34.655 which rounds to 35 ft.
