zaharov [31]

Answer:

From the above attachment we can conclude that the sum of the angle 'b' and 40° is 90° (right angle)

$b + 40 ^\circ = 90 {}^{ \circ} \\ b = 90 {}^{ \circ} - 40 {}^{ \circ} \\ \boxed{ b = 50 {}^{ \circ} }$

b = 50° is the right answer.

The triangle to solve for has a leg or 12 feet, hypotenuse of 20 feet, so solve for Pythagoras $a^{2} + b^{2} = c^{2}$ for a

$a = \sqrt{c^{2} -b^{2}}$

a = 16 feet
