BCF is similar to EDF in a 3:1 ratio so BF:FD = 3:1 also therefore the area of BEF is also 3x area of EDF = 3. Then since the BC:ED = 3:1 => AE:ED 2:1 and the area of ABE is 2x AED = 2(3 + 1) = 8. So the total is AED + BEF = 8 + 3 = 11
Triangle BFC is similar to DFE with ratio of similarity= 1/3 So ratio ... | 677.169 | 1 |
If we want to calculate the height of an equilateral triangle, and we know its side length is 100, we can use the formulae length of the adjacent multiplied by the tangent of the angle is equal to the opposite.
In JavaScript, we can do this with the following:

50* Math.tan(degToRad(60));
We use our degToRad() fu... | 677.169 | 1 |

Since FG is parallel to AB we can see that FE bisects < AFG. So E is the ex centre of Tr. FGC. Hence EG bisects right < BGF and so < EGB = 45. But < EBG = 45 and so BG= 2r where r is the in radius = altitude of isoceles Tr. BEG
Very simple. AB and GF are both tangents to the incircle. Let X be a point such that A... | 677.169 | 1 |

A vector $\vec{v}$ in the first octant is inclined to the $x$-axis at $60^{\circ}$, to the $y$-axis at 45 and to the $z$-axis at an acute angle. If a plane passing through the points $(\sqrt{2},-1,1)$ and $(a, b, c)$, is normal to $\vec{v}$, then :
A
$a+b+\sqrt{2} c=1$

Step 2: Find the Common Side
Next, look for the common side. Adjacent angles will always have one side (or ray) that is the same.
Step 3: No Common Interior Points
Finally, make sure that the angles do not have any common interior points. This means that they do not overlap each other.
For example, if you have a sh... | 677.169 | 1 |
Le Bron has three pins, labeled A, B, and C, respectively, located at the origin of the coordinate plane. In a move, Le Bron may move a pin to an adjacent lattice point at distance 1 away.
