WebArea = ½ × base × height. We know the base is c, and can work out the height: the height is b × sin A. So we get: Area = ½ × (c) × (b × sin A) Which can be simplified to: Area = 1 2 … WebSolution Let bisector of ∠O meet AB at point D and bisector of ∠A meet BO at point E ∴ Point D divides seg AB in the ratio l (OA) : l (OB) and point E divides seg BO in the ratio l (AB) : l (AO) Let l be the incentre of ∆OAB. By distance formula, l (OA) = ( 0 - 6) 2 + ( 0 - 0) 2 = 6 l (OB) = ( 0 - 0) 2 + ( 0 - 8) 2 = 8

WebApr 10, 2024 · We consider a polygon OBCDA with coordinates A ≔ (a, 0), B ≔ (b, c), C ≔ (c 1, c 2), D ≔ (d 1, d 2); see Fig. 2. Without loss of generality, we can suppose 0 < b < a < c 1 < d 1. The proof for the general polygon is the same as in this case. Dividing the polygon into triangles is a crucial step to achieve the proof. WebIf the line 3 x + 4 y − 2 4 = 0 intersects the x − axis at the point A and the y − axis at the point B, then the incentre of the triangle O A B, where O is the origin, is: Medium View solution
Webbecause 4 and 5 is in both the denominator and numerator. Mathematically we can explain it like this: You have the equation y = 10 - (5 * 2)/2 We can rewrite (5 * 2)/2 = 5 * (2/2) Here you can see that 2/2 = 1 So (5 * 2)/2 = 5 * 1 = 5 Your equation can be rewritten as y = 10 - (5 * 2)/2 = 10 - 5 * (2/2) = 10 - 5 * 1 = 10 - 5 1 comment ( 2 votes) WebMay 26, 2024 · 1.
