**Answer:**

72

**Step-by-step explanation:**

<1 and <2 are not equal to each other

Let the angle directly above angle 2 (on the right side of the line) be angle 3

<1 and <3 are corresponding angle, which means they are equal

<2 and <3 are supplementary angles since the form a line

<2 + <3 = 180

We know <1 = <3

<1 + <3 = 180

We are given <1 = 2x+12 and <2 = 3x+18

2x+12 + 3x+18 = 180

Combine like terms

5x+30 = 180

Subtract 30 from each side

5x+30-30 = 180-30

5x= 150

Divide each side by 5

5x/5 = 150/5

x=30

<1 = 2x+12

Substitute 30 in for x to find angle 1

= 2*30 +12

=60+12

= 72

The answer is d because 4+8=12 and they are 4 units away from eachother:)

**Answer: 60**

**Step-by-step explanation:**

144 beads divided by 3 would equal how many black beads there are, which is 48. 144 beads divided by 4 would be how many purple beads there are. which is 36. You would add the black beads and the purple beads, or 36 + 48, to get the total of both. 36 + 48 = 84. You would take the 144 beads total minus the 84 black and purple beads, which is 60.
