A right triangle has one angle that is 90 degrees (always) Adding up all three angles should equal 180 degrees If we have one angle that is 28 degrees, we just subtract 28 from 90 (62 degrees) and that is the unknown angle. If we have a right triangle with a hypotenuse of 6 and an opposite of 4 with an unknown angle, how do we find that angle?

Practice questions. If 3 x = 4 y and 5 y = 6 z, then; For which of following values for x is log 6 4 + log 6 x = 2?; Answers and explanations. The correct answer is Choice (B). Looking at the answer choices tells you you’re dealing with a logarithm problem.

Jun 12, 2014 · (answer) Using the same plane (F-22) the same weight (57,600 pounds) and angle of attack, what should be its cruising speed at 36,000 feet? While descending from 42,000 feet to 36,000 feet the plane covers a horizontal distance of 40 nautical miles. What is the decent angle in degrees?

A triangle has an angle measuring $90^\circ$, an angle measuring $20^\circ$, and a side that is 6 units long. The 6-unit side is in between the $90^\circ$ and $20^\circ$ angles. Sketch this triangle and label your sketch with the given measures.

We know from an important trigonometric identity that cos2A+sin2A = 1 so that by rearrangement sin2A = 1− cos2A. So using this result we can replace the term sin2A in the double angle formula. This gives cos2A = cos2A −sin A = cos2A −(1− cos2A) = 2cos2A− 1 This is another double angle formula for cos2A.
