Help me please if you can!!

The measure of the 3 angles is  36.9, 53.1 and 90 degrees.

Step-by-step explanation:

5^2 = 3^2 + 4^2  so , by the inverse of Pythagoras Theorem, this is a right angled triangle so one angle is 90 degrees.

We can find the other 2 angles using trigonometrical ratios.

One angle  will have a sine of 3/5 and the other a sine of 4/5.

So the angles are arcsin 3/5 = 36.9 degrees and the other is arcsin 4/5 = 53.1 degrees.

The scale factors is 2.5.

Step-by-step explanation: The scale factor what you multiply or divide to get the size of the copy. 4 x 2.5 = 10
