Find y. Round to the nearest tenth: 31° у х 400 ft y = [ ? ]ft

1 answer:

4 0

Y equals 240.3 ft. This is because the bottom angle of the triangle is an alternate interior angle to 31 degrees, so it is also 31 degrees. You can then create the equation tan31=y/400. To find y multiply each side by 400 and you’ll get 240.344
