Angle U and Angle V are complementary angles. If Angle U is three less than twice Angle V, what are the measures of the angles?

B is in the interior of angle AOC. C is in the interior of angle BOD. D is in the interior of angle COE. The measure of angle AOE is 162 degrees, COE is 68 degrees, and the measures of angles AOB, COD, and DOE are all equal. The question is to find the measure of angle DOA. (...

I'm assuming this quadrilateral, ABCD is in a plane and not on a sphere. Given the information you have provided, the numbers 6 and 10 on two of the sides has nothing to do with the question. In EVERY quadrilateral, no matter the shape, the sum of the four angles is ALWAYS.

1. Recall that the formula for converting deg F to deg C is C = (5/9)*(F - 32) Substituting, C = (5/9)*(189 - 32) C = (5/9)*(157) C = 87.2 deg Celsius To convert to Kelvin, K = C + 273.15 K = 87.2 + 273.15 K = 360.37 Kelvin 2. K = C + 273 K = -248.6 + 273.15 K = 24.55 Kelvin (...
