hi,
Express the ratios in fractional form, that is
= ( cross- multiply )
y + 3 = k(y + 5) ← distribute
y + 3 = ky + 5k ( subtract ky from both sides )
y - ky + 3 = 5k ( subtract 3 from both sides )
y - ky = 5k - 3 ← factor out y from each term on the left side
y(1 - k) = 5k - 3 ← divide both sides by (1 - k)
y = 5k- 3
____
1 - k
Answer:
1st: 116°
2nd: 64°
Step-by-step explanation:
Supplementary angles add up to 180 degrees. We can make the first supplementary angle be represented by: 2x - 12 and the second supp. angle be represented by x.
Make both of these expressions add up to 180.
(2x - 12) + (x) = 180
Combine like terms.
3x - 12 = 180
Add 12 to both sides.
3x = 192
Divide both sides by 3.
x = 64
Substitute 64 for x into the first supp. angle's expression.
2(64) - 12 = 116
The first supp. angle is 116 degrees and the second is 64 degrees.
