First identify the angle RELATIONSHIP, then find the measure of the angle indicated in bold.

Same-side interior angles

m∠ = 80°

Step-by-step explanation:

Step 1: Set up equation

x + 85 + x + 105 = 180

Step 2: Combine like terms

2x + 190 = 180

Step 3: Isolate x and solve

2x = -10

x = -5

-5 + 85 = 80°

a) 32pie square meters

step-by-step explanation:

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
