Distance between T(80, 20) and U(20, 60) = sqrt((20 - 80)^2 + (60 - 20)^2) = sqrt((-60)^2 + (40)^2) = sqrt(3600 + 1600) = sqrt(5200) = 72.11 units
Distance between T(80, 20) and V(110, 85) = sqrt((110 - 80)^2 + (85 - 20)^2) = sqrt((30)^2 + (65)^2) = sqrt(900 + 4225) = sqrt(5125) = 71.59
Distance between U(20, 60) and V(110, 85) = sqrt((110 - 20)^2 + (85 - 60)^2) = sqrt((90)^2 + (25)^2) = sqrt(8100 + 625) = sqrt(8725) = 93.41
Therefore, shortest distance for the trip = 71.59 + 93.41 = 165 units.
Some people call 'n' "zero" for the first term, others call 'n' "1".
-- If n=0 for the first term, then T(0) = 0² + 3 = 3 .
-- If n=1 for the first term, then T(1) = 1² + 3 = 4 .
Missing sides or angles??
If it's missing sides... Then using sine rule
A/ sin A = B/ sin B
Let sin A =30° and A=8
Let sin B=60° and B =?
Hence 8/sin 30°=B/sin 60°
Multiplying 8 x sin 60 =B sin 60
6.928 = 0. 5B
Dividing both sides by 0.5
Hence B= 13.856
doing same for side c
Let sin A =30° and A =8
Let sin c =90° and C =?
Hence 8/sin30° = C/sin 90
Sin 90° x8 =. 0.5c
Sin 90=1
1x8 =0.5c
Dividing both sides by 0.5 gives 16
Hence C=16
Answer:
An equilateral triangle is a triangle in which all three sides are equal. An equilateral triangle is also equiangular, in which all three internal angles are also congruent to each other and are each 60°.
Parallelogram and rhombus possibly.
Trapezoid.
