WebSep 6, 2024 · If the length of the third side of the triangle PQR is $\sqrt{m}$ cm, then the largest possible value that $'m'$ can take is? At first I thought the information given i.e. $\cos(3P)+ \cos(3Q)+ \cos(3R) = 1$ to be a distraction and I went with the usual way to solve this problem that sum of two sides is always greater than the third side. So; WebIn a PQR, if 3 sinP + 4 cosQ = 6 and 4 sinQ + 3 cosP = 1, then the angle R is equal to: A 43π B 65π C 6π D 4π Medium Solution Verified by Toppr Correct option is A) We have, … smart fortwo coupé 60kwed

WebIn a Δ P Q R, if 3sinP+4cosQ=6 and 4sinQ+3cosP = 1, then the angle R is equal to (a) 150 o (b) 30 o (c) 45 o (d) 135 o 13 ) In a Δ P Q R, ∠ R = π 2, i f t a n ( P 2) a n d t a n ( Q 2) are the roots of ax 2 + bx + c = 0, a ≠ 0, then (a) b = a + c (b) b = c (c) c = a + b (d) a = b + c 14 ) WebA triangle has three sides, three vertices, and three interior angles. The angle sum property of a triangle states that the sum of the three interior angles of a triangle is always 180°. Observe the triangle PQR given above in which angle P + angle Q + angle R = 180°. WebJan 31, 2024 · To calculate the area of an equilateral triangle, you only need to know the side: area = a² × √3 / 4. Since √3 / 4 is approximately 0.433, we can formulate a quick recipe: to approximate the area of an equilateral triangle, square the side's length and then multiply by 0.433. Although we didn't make a separate calculator for the ... hills barbarians cc
