can you please help question 8 Question 8 ?BCD is an isosceles triangle, with BC-BD. Which...
hw question help please!! 5. (8 pts) An isosceles right triangle is as shown in the figure. The hypotenuse is increasing at a rate of 0.1 ft/s. When the area of the triangle is 8 square feet, at what rate is the leg increasing? Do not use any calculator. y x X
can you please please help me with these proofs R Cand CoDNder the triangle AABC and M and NIwopaints such thatM PrOve that MEMAN kBA) M MBC)m ACRI. Let AABC be a triangle with AB< AC and let D be a point such that A C - D. Show that for every point M with B- M- C we have m(< ABM) +m(< BMA)> m(< CMD)+m(< MDC) Prove that if in the triangle AABC the altitudes AD and BE (where...
can help me to answer question b and c ,11, 12, 3.13 Simplify the following expressions to (1) sum-of-products and (2) products-of-sums: (a) A'C' +B'C' +BC' + AB (b) ACD' + C'D + AB' + ABCD (c) ale (A' + B+ D')(A' + B' +C')( A' B' +C)(B' +C+ D') (d) BCD'+ABC' +ACD
I need help doing a doing two column for these two propositions. Book 1 Proposition 7: Given two straight lines constructed from the ends of a straight line and meeting in a point, there cannot be constructed from the ends of the same straight line, and on the same side of it, two other straight lines meeting in another point and equal to the former two respectively, namely each equal to that from the same end. Book 3 Proposition 14:...
4. The following figure shows triangle AABC with side lengths AB = 10, BC = 8, and CA = 5. DE is constructed to be parallel to AB and to originate at point D, the midpoint of AC. C X10 D Ε B A Write the lengths for the segments listed below. BE = ED= DA=
Do not use I=delta/S!!! Use law of cosines Here is the question: Let r be the radius of the incircle of triangle ABC on the unit sphere S. If all the angles in triangle ABC are right angles, what is the exact value of cos r? Note in spherical geometry the angles sum is>180 Using below picture (this is what we are given), we should know angle b and the angle at the perpendicular. If we find the length on...
can you do 11 and 12 please. E C 7. If AE-3, AB 5, and AD 4, find AC. 8. If AD-5, AB = 8, and AC = 7, find AE. 9. If BD = 3, EC = 4, and AC-9, find AD. 10. If AD = EC, DB = 4, and AE = 9, find AD. 11. If DE5, BC 7, and AD4, find AB. 12. If ED = 7, BC = 10, and AE = 2 + EC,...
please help with all questions not partly Question 10 Which of the folowing statements is/are true A. A sphere bas radius 3s units.

The only ideas that can be used include: area ABCI-RA2(A+B+C-lpi), the Pythagorean theorem: Cos c cos a cos b. Vectors-dot product cross product, sin A-sin a/sin c; cos A-cos a sin b/sin c; spherical law of sines, spherical law of cosines for sides and spherical law of cosines for angles Let r be the radius of the incircle of triangle ABC on the unit sphere S. If all the angles in triangle ABC are right angles, what is the exact...
Can someone help me and tell me which ones are wrong and if they are wrong can you tell me which is the correct answer please!!! i will forever be grateful <3 How does AC in OE relate to DF in OF? A D F NE В Н C AC is congruent to DF AC is two times longer than DF AC is three times shorter than DF AC is four times longer than DF Given that IG LFT, which...
