The base angles are both equal to (180-70) / 2 = 55 degrees
and 1/2 base = 123
so we have tan 55 = a / 123 where a = altitude
a = 123 * tan55 = 175.66
Square root of 121 is 11.
11-7=4
A side of the original square is 4 feet.
Answer
9.327
16*16= 256
13*13=169
256-169=87
87 squared=9.32737905309
9.32737905309 ROUNDED TO NEAREST THOUSANDTH= 9.327
