Igoryamba

Answer:

Rotation, then reflection, then translation

Step-by-step explanation:

The sequence of three rigid transformations that is used to map Triangle ABC onto TriangleA"B"C" are what we called ROTATION ,REFLECTION AND TRANSLATION

ROTATION can be defined as the process or waysbin which an object tend to rotate about a fixed point without the object changing either its size or shape.

REFLECTION occur in a situation where an object is been flipped across a line without the object changing either its size or shape.

TRANSLATION can be defined as the process or ways of sliding a figure in any or various direction without the figure changing either its size or shape .

Zolol [24]

Answer:

10 people bought both strawberry and peach cones

Step-by-step explanation:

Given that there are two types of ice cream cones - strawberry and peach. You and 24 of your closest friends are going to buy ice cream cones.

Assuming that each one had atleast one ice cream we get

$n(AUB) =24+1 =25$

A - no of people bought straw berry

B - no of people bought peach cones

n(A) = 15 and n(B) =20

Hence we have

$n(AUB)=n(A)+n(B)-n(AB)\\25= 15+20-n(AB)\\n(AB) = 10$

10 people bought both strawberry and peach cones
