Use the figure to find the measures of Z1 and 22

∠ 1 = 149°, ∠ 2 = 31°

Step-by-step explanation:

∠ 1 and 31° are same-side interior angles and are supplementary, thus

∠ 1 = 180° - 31° = 149°

∠ 2 and 31° are alternate angles and congruent, thus

∠ 2 = 31°

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✌✌✌
