there is not enough information to provide an answer. usually there is a diagram involve with the question (you can post that in the discussion area). there is an infinite amount of different shapes that can have it's 4th angle measuring 22 and with an arc.

Find the acute angle between the diagonals of rectangle whose side are 5cm and 7cm methods?
Name the rectangle ABCD,letting the larger side be AB(7cm) and the smaller side be AC(5cm). Draw the two diagonals across the rectangle. Name the point of intersection of the two diagonals (which resembles an X) F. Name the midpoint between the smaller side AC, to be E. AFC is the acute angle you are looking for, angle AFE is half of that. So AFE is a right angled triangle and AE is equal to half of 5cm, which is 2.5; FE is equal to half of 7cm, which is 3.5. Now, taking triangle AFE, Tan AFE=2.5/3.5 AFE=35.537 degrees Since the angle AFE is half of the acute angle AFC that you are looking for, multiply AFE into two So, 35.537*2 =71.075 degrees =71.1 degrees (to 1 decimal place) AFC= 71.1 (ANS)
What is the length to the nearest tenth of the hypotenuse DF of a right triangle DEF if FE is 13 units long and angle F is 34 degrees?
Without seeing the diagram your question (as originally written) was incomplete and impossible to answer. If you had described your question (by rewriting it as I did) instead of blindly copying it, then the Answers community would have had all the necessary information to be able to answer your question and you would have got your homework done for you quicker. In fact, in rewriting the question you may actually have realised what was needed to be calculated and done it yourself - a very useful skill in being able to extract the required mathematics from the given information. Anyway, what is now obvious from the rewritten question is you have is the cosine ratio: cosine = adjacent/hypotenuse → cos F = FE / DF → DF = FE / cos F As you didn't bother to give us the required information, I can't be bothered to fill in the numbers and calculate the required value - you can do that. ----------------------------------------------------------------------------- What I was taught at pre-secondary school (some 40 odd years ago) to help remember the different trigonometric ratios: In a right angle triangle there are three sides to an angle: Opposite - the side opposite the angle Adjacent - the side adjacent to the angle which is not the hypotenuse. Hypotenuse - the side opposite the right angle There are three ratios: Tangent = Opposite / Adjacent Sine = Opposite / Hypotenuse Cosine = Adjacent / Hypotenuse To remember them, use this nonsense rhyme: Two Old Arabs Soft Of Heart Coshed Andy Hatchett The initial letter of each word in each line gives the ratio: Two Old Arabs → T = O / A → Tan = Opp / Adj Soft Of Heart → S = O / H → Sin = Opp / Hyp Coshed Andy Hatchett → C = A / H → Cos = Adj / Hyp
