I need the value of x

x = 64°

Step-by-step explanation:

180° in half a circle or a line.

There is also 180° in a triangle.

So the other 2 angles of the triangle equal x.

34° + 30° = 64°

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✌✌✌
