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

,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
c++ 17 please help!! A triangle can be of three types-one in which all the sides are equal, or one in which only two sides are equal, or one in which all the three sides are unequal. You are assigned to write a program that allows the user to enter the three sides of a triangle. The program should use three double variables to store the three sides of the triangle. The program should also be able to print the...
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...

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...
