ΔABC is an isosceles right triangle. Use the isosceles triangle base angles theorem and the sum of the interior angles of a triangle to determine the measures of ∠ACB and ∠ABC. answers : ∠ACB = 45° and ∠ABC = 90° ∠ACB = 45° and ∠ABC = 45° ∠ACB = 90° and ∠ABC = 90° ∠ACB = 90° and ∠ABC = 45°

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✌✌✌

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
