In a 45 -45 -90 triangle, the ratio of the hypotenuse to the length of a side is...?

The areas of two similar triangles are 72dm2 and 50dm2. the sum of their perimeters is 226dm. what is the perimeter of each of these triangles?

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^x

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.
