We know the two angles add up to 180
5x + 134 + 2x + 32 = 180
Combine like terms
7x + 166 = 180
Subtract both sides by 166
7x = 14
Divide both sides by 7
x = 2
Have an awesome day! :)
Answer:
1. 4/7 = 16/28
Check:
(4/7)(4/4) = 16/28 = 16/28
2. 40/15 = 8/3
Check:
(40/15)/(5/5) = 8/3
3. 15/6 = 5/2
Check:
(15/6)/(3/3) = 5/2
4. 8/11 = 56/77
Check:
(8/11)(7/7) = 56/77
5. 9/2 = 63/14
Check:
(9/2)(7/7) = 63/14

Answer:
Jada and lin are comparing inches and feet.
Let I denote inches and F denote feet.
It is given that
I =k F or F=m I
So, I/F=k or m=F/I
As we know 1 feet = 12 inches
constant of proportionality i.e k=1/12
In case 2, constant of proportionality=12/1=12
So, Jada must have calculated ratio of feet to inches while Lin has calculated the ratio of inches to feet.
Step-by-step explanation:
Step 1- Multiply both sides by 8.
Step 2- Simplify 3 x 8 to 24.
Answer = x > 24
