Ineed to know what is the answer of 10 + 19

29

Explanation: Add 10 and 19 together...

I added 19 then 10

answer should be 29

easier way if you add 10 and 10 first

then add 9 later on

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3

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✌✌✌
