How many significant figures are there in the number 10.76?

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.

Atriangle abc has two side lengths of 28 ft. and 24 ft. if angle c is 91°, what's the measurement of angle b?
