Answer: 28.33 Celsius and 301.483 Kelvin
83°F − 32) × 5/9 = 28.333°C
(83°F − 32) × 5/9 + 273.15 = 301.483K
Answer:
x = 30°
Step-by-step explanation:
So the total angle of a quadrilateral is 360°.
Your goal is to find x which associate numbers in each corner.
The equation to the quadrilateral is this:
a + b + c + d = 360°
a = ∠ABC = 4x
b = ∠BCD = 3x
c = ∠CDA = 2x
d = ∠DAC = 3x
∠ABC + ∠BCD +∠CDA + ∠DAB = 360°
4x + 3x + 2x + 3x = 360°
7x + 5x = 360°
12x = 360°
x = 360 ÷ 12
x = 30°
