Step-by-step explanation:
Given
F = (K - 273.15) + 32
Multiply through by 5 to clear the fraction
5F = 9(K - 273.15) + 160 ( subtract 160 from both sides )
5F - 160 = 9(K - 273.15) ← distribute
5F - 160 = 9K - 2458.35 ( add 2458.35 to both sides )
5F + 2298.35 = 9K ( divide both sides by 9 )
K =
(b)
When F = 180, then
K =
=
=
≈ 355.37 ( to the nearest hundredth )
Answer:
A = 32°, a = 19, b = 14, B=22.98°, C = 125.02°, c = 29.36
Step-by-step explanation:
We have two sides of the triangle and we have an angle.
A = 32 °, a = 19, b = 14
We use the sine theorem to find the angle B.
We know that according to the sine theorem it is true that:
We know that the sum of the internal angles of a triangle is always equal to 180.
So:
Finally we find the c side
