I need help, please help

a² + b² = c²

1. 45² + 36² = c²

2025 + 1296 = c²

3321 = c²

√3321 = √c²

57.6 = c

2. a² + 4.5² = 12.5²

a² + 20.25 = 156.25

a² + 20.25 - 20.25 = 156.25 - 20.25

a² = 136

√a² = √136

a = 11.7

Step-by-step explanation:

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

where did you get them? if you picked from the grass, is is probably poisonous.
