Alecsey [184]

Answer:

C. m/1=m/2=54

Step-by-step explanation:

these two angles are equal hence:

5x-16=4x-2=-16+2 =-14

4x-5x=-x

-x=-14=x=14

A square has a 40-cm diagonal.How long is each side of the square? Round to the nearest tenth of a centimeter
Masja [62]

Answer:

28.3 cm

Step-by-step explanation:

Let x represent the length of one side of the square.  Then, by the Pythagorean Theorem,

x^2 + x^2 = (40 cm)^2, or

2x^2 = 1600 cm^2.

Thus, x^2 = 800 cm2, and x, the length of one side, is √800, or 28.3 cm to the nearest tenth of a cm.
