So let's see if we can do that. (a) The Venn diagram below shows the number of students who study History and French in a class of 30 students. Let's label the points P(a,b), R(x, 0) and Q( y,y). math. Physics. Let angle QOR = 2x, where x is an acute angle a) show that the area A of Triangle PQR is given by A=sinx(cosx + 1) b) Hence show that, as x varies, triangle PQR has its maximum possible area when it is equilateral. (2) At point P draw another line segment PS making an angle of 120° with PQ. m . (8) (e) Find a value of for which S has its greatest value. Then, fill in the blanks with the numbers 8,5 ,133 and . f(x) is a parabola, and we can see that the turning point is a minimum.. By finding the value of x where the derivative is 0, then, we have discovered that the vertex of the parabola is at (3, −4).. write the length of the hypotenuse as a function of x. find the vertices of the triangle such that its area is a minimum. We know that, the sum of the lengths of any two sides of a triangle is always greater than the length of the third side. (a) Write an equation that could be used to answer the question above. Following the rule, the y-value of P' is 6-16= -10. Mar 4, 2019 [Answer] 8. ... (1,2). In triangle ABC, the measure of angle A is 25° and the measure of angle B is gr... in a triangle ABC, the right angle is at B. Since the function has minimum value at, the function F(x) is decreasing in and increasing in. ... consider the right angled triangle PQR. Join R to Q. From the Pythagoras theorem, PR 2 = PQ 2 + RQ 2. scalene Inequalities for the area of a triangle 237 * * * 238 §9. Thus, we get. AD is the median to the side BC in triangle ABC and PS is the median to the side QR intriangle PQR. Note angles x and y. Because if we're able to solve for a using r, then we can then put that value of a in here and we'll get the area of our triangle. We know that, the sum of the lengths of any two sides of a triangle is always greater than the length of the third side. Step 1 : Introduction to the question "8. #1 find the value of x if RS = 4(x-3)+6 and RT = 5(2x-6). (3) (d) Find the value of when S is a local minimum, justifying that it is a minimum.
