Given that triangle ABC has been dilated to form triangle A'B'C' and the vertices of ABC are A(5,3), B(3,7), C(1,4) and vertices of A'B'C' isA'(7.5, 4.5), B'(4.5, 10.5), C'(1.5,6)
then the scale factor for dilation will be as follows:
Taking corresponding vertices SAY A (5,3) and A'(7.5, 4.5)
the scale factor will be:
7.5/5=4.5/3=1.5

Can you help me with these questions<br>​
dlinn [17]

Answer:

see below (I hope this helps!)

Step-by-step explanation:

41. √20 = √4 * 5 = √4 * √5 = 2√5

43. The sum of interior angles in a triangle is 180°, therefore, x = 180 - (75 + 64) = 41°.

45. 15 + 5(2x - 3) = 15 + 5(2x) + 5(-3) = 15 + 10x - 15 = 10x

47. Complementary angles have a sum of 90°, therefore, x = 90 - 48 = 42°.
