5. Statement:

Step-by-step explanation:

Given, triangle STU is an equilateral triangle.

To prove that

Proof:

1. Statement:

Reason: Given in question .

2. Statement:

Reason: By using reflection proeperty of rotation.

3. Statement: is an equilateral triangle.

Reason: given.

4. Statement:

Reason: Sides of equilateral triangle STU.

5.

Reason: AAS congruence property of triangle.

6. Statement:

Reason: CPCT ( corresponding parts of congruence triangles).

i really dont know

step-by-step explanation:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
