A right triangle has legs of length 10 and b, and a hypotenuse of length c. The perimeter of the triangle is 30. Compute c.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

∠cbe and ∠deb are same-side interior angles.
