Match the missing sides for each triangle using the special right triangle theorems.

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

Can someone me and do the problem plz so i can understand it more better

(05.08a)triangle abc is transformed to similar triangle a′b′c′ below: a coordinate plane is shown. triangle abc has vertices a at 2 comma 6, b at 2 comma 4, and c at 4 comma 4. triangle a prime b prime c prime has vertices a prime at 1 comma 3, b prime at 1 comma 2, and c prime at 2 comma 2. what is the scale factor of dilation? 1 over 2 1 over 3 1 over 4 1 over 5
