Question

A shed is 8ft wide. One raft we makes an angle of 30 degrees with the horrizonatal on one side of the roof. A raft er on the other side makes an angle of 70 degrees with the horizontal.calculate the length of the shorter, rafter to the nearest

Answer 1

Draw a figure. Use the law of sines.

The third angle is 80°.

x/sin 30 = 8/sin 80

Since sin 30° = 1/2: x = 4/sin 80°

I will let you get the nececessry sin and do the division.
