How do i find measurements of angle 1-5?

∠1 + 52° = 180° (Opposite angles are supplementary)

=> ∠1 = 180° - 52°

=> ∠1 =  128°

∠2 = 52° (Alternate interior angles)

∠3 = 47° (Alternate interior angles)

∠4 = 180° - ∠3 (Supplementary angles)

=> ∠4 = 180° - 47°

=> ∠4 = 133°

∠5 = 180° - (52° + 47°) (Supplementary angles)

=> ∠5 = 180° - 99°

=> ∠5 = 81°

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
