Answer:
the other two sides are 31.11 feet and 31.11 feet
Step-by-step explanation:
since two angles are 50°, the triangle is isosceles with the other two sides being equal in length.
A right triangle is formed by a line from its peak down & perpendicular to
the 40 foot side. It's hypotenuse is the unknown (x) and it's base is 40/2 = 20 feet.
cos 50 = 20/x
0.6428 = 20/x
x = 31.11 feet
