Arectangle has an area of 50 centimeters squared. the dimensions of the rectangle are multiplied to form a new rectangle with an area of 200 centimeters squared. by what number were the dimensions multiplied?

2

Step-by-step explanation:

Let A₁ = the original area a

and A₂ = the new area

and n = the number by which the dimensions were multiplied

A₁ = lw

A₂ = nl × nw = n²lw

A₂/A₁ = (n²lw)/(lw) = 200/50

                        n² = 4

                        n = 2

The dimensions were multiplied by a factor of 2.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
