we know two things from this problem that aren't really given.
1: Since it's isosceles, we know that both it's legs are the same length.
2: Since it's a right triangle, we know the square of it's hypoteneuse is equal to the sum of the square of it's legs.
So, we know:
A(7)^2 + B(7)^2 = C^2
49 + 49 = C^2
98 = C^2
sqrt(98)=C
Sqrt(49)*Sqrt(2)=C
7Sqrt(2)=C

According to your information, the perimeter is the sum of length of all sides. So, the perimeter is Perimeter=(2x + 9) + (2x + 9) + (3x) Since the perimeter is known to be 60 inches, 60 = (2x + 9) + (2x + 9) + (3x) or, 60 = 2(2x + 9) + 3x = 4x + 18 + 3x = 7x + 18 60 - 18 = 7x 42 = 7x 42/7=x x=6 Therefore, x = 6

Impossible without knowing the angle at the apex. All that can be said is that it's between 0.000000000000000.....001 cm and 13.9999999999999... cm

Don't you think you would be better trying to work through some of these problems yourself rather than just asking for the answers? You'll never learn that way.

a^2+b^2=c^2
so if this is correct
49+49=98
square root of 98
