Question

I NEED HELP PLEASE!!!!

Answer 1

A

∆

B C

Angle abc = 74°

Angle bca = x

angle cab = 53°

from angle sum property

A + B + C = 180

53 + 74 + x = 180

x = 53

Angle bca = 53°

Angle cab = 53°

so we know if in a ∆ angles are equal then there opposite line must be equal

so Line BA and BC are equal

simpley calculate volume

volume of cube = side ³

= 2³ = 8m³
