Answer:
<h2>m∠EFG = 126°</h2><h2>m∠GFH = 54°</h2>
Step-by-step explanation:
If ∠EFG and ∠GFH are a linear pair, then m∠EFG + m∠GFH = 180°
(look at the picture).
We have
m∠EFG = 5n + 16
m∠GFH = 2n + 10
Substitute:
(5n + 16) + (2n + 10) = 180 <em>combine like terms</em>
(5n + 2n) + (16 + 10) = 180
7n + 26 = 180 <em>subtract 26 from both sides</em>
7n + 26 - 26 = 180 - 26
7n = 154 <em>divide both sides by 7</em>
7n/7 = 154/7
n = 22
Insert the value of n into expressions that specify angle measures:
m∠EFG = 5n + 16 → m∠EFG = 5(22) + 16 = 110 + 16 = 126°
m∠GFH = 2n + 10 → m∠GFH = 2(22) + 10 = 44 + 10 = 54°
0.6222... is a recurring decimal at the digit '2'
let x = 0.62222....
multiply x by 10 ⇒ 10x = 6.2222.... [we multiply by 10 to leave the recurring digits after decimal point]
multiply x by 100 ⇒ 100x = 62.2222... [we multiply by 100 so that we can again leave the recurring digit after decimal point]
subtract 10x from 100x
100x - 10x = 62.2222... - 6.2222...
90x = 56
x = 56/90
x = 28/45
