A same side interior angle of two parallel lines is three times the other same side interior angle. Find the measures of these two angles.

45 , 135

Step-by-step explanation:

As we know the property of interior angle if there are two parallel lines i.e The sum of two angle is 180.

Let the First angle be x then other angle 3x

So

x + 3x= 180 [ By the interior property the sum of two angle is 180]

     4x=180

Therefore Other angle is 3*45= 135  

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✌✌✌
