1. Joshua has a ladder that is 15 ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 14.8 ft above the ground. For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 70°. Will the ladder be safe at this height (2 points)? Show your work and draw a diagram to support your answer

Unsafe; angle with ground > 70°.

Step-by-step explanation:

Data:

a = 15    ft

b = 14.8 ft

A = 90°

Calculation:

We can use the Law of Sines.

The ladder will be unsafe because its angle with the ground is greater than 70°.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
