This is a 1, 1, √2 triangle, as the two leg sides are congruent.
the 1 side = 12 in measurement
Multiply 12 with √2
12 x √2 = 12√2
12√2, or (A) is your answer

Answer:
a) Similar triangles are triangles with the same shape but not necessarily the same size
b) 15/45 = 8/x
1/3 = 8/x (simplify the 15/45)
x = 8 * 3 (cross multiplication)
x = 24
c) y^2 = 15^2 + 8^2 (Pythagoras theorem)
y = *square root of* 15^2 + 8^2
y = 17
1/3 = 17/z
z = 17 * 3 (cross multiplication)
z = 51
