Answer:
• linear angles
• supplementary angles (all linear angles are supplementary)
Step-by-step explanation:
If the angles share a side and are measured in opposite directions from that side, the non-common edges of these angles form a straight line, so these angles are sometimes called "linear" angles.
Since their sum is 180°, they are always "supplementary" angles. (Supplementary angles need not share a vertex or a side.)
Step-by-step explanation:
1. 1/6d - 8 = 5/8
1/6d -8 + 8 = 5/8 + 8
1/6d = 69/8
1/6d / 1/6 = 69/8 / 1/6
d = 51.75 or ![51\frac{3}{4}](https://tex.z-dn.net/?f=51%5Cfrac%7B3%7D%7B4%7D)
2. 3x - 4 + 5x = 10 - 2z
8x - 4 = 10 - 2z
8x - 4 + 4 = 10 - 2z + 4
8x = 14 - 2z
8x / 8 = (14 - 2z) / 8
x = ![\frac{14 - 2z}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B14%20-%202z%7D%7B8%7D)
3. 7(c - 3) = 14
7(c - 3) / 7 = 14 / 7
c - 3 = 2
c - 3 + 3 = 2 + 3
c = 5
4. 11(m / 22 + 3 / 44) = 87
m / 22 + 3 / 44 = 87 / 11
m / 22 + 3 / 44 = 348 / 44
m / 22 = 345 / 44
m = 172.5
5. ck + 5k = a
k(c + 5) = a
k = ![\frac{a}{c+5}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bc%2B5%7D)
