Answer:
20°
Step-by-step explanation:
ΔCAD
BD=CD
∠BCD=50°, ∠BAD= 30°, x= ?
------------
BD=CD ⇒ ∠CBD= ∠BCD= 50° ⇒ ∠BDC= 180°- 50°×2= 80°
∠ADC= 180° - (50°+30°)= 100°
x= ∠ADC - ∠BDC= 100° - 80°= 20°
x= 20°
K = 
(F - 32) + 273.15
To cancel out the 5/9, you can either multiply everything by the denominator and divide it down, or multiply everything by the reciprocal of the fraction (
. Multiplying by the reciprocal is definitely easier if you can use a calculator:
K = (F - 32) + 491.67
Subtract 491.67 from both sides:
K - 491.67 = F - 32
Finish off by adding 32 to both sides:
K - 459.67 = F
Therefore, F = K - 459.67.
Hope this helps! :)
One solution. 220/-10x = -22
