Answer:
area of traingle=1/2(sin130×AB×AC)
85×3=sin130×AB×AB
255=76×AB²
255/76=AB²
√332.88=AB
AB=18.24
AC=18.24
Step-by-step explanation:
Hope this helps.
Let s represent the short side of the triangle. The long sides of the triangle are each s+1, and the triangle's perimeter is
... s + (s+1) + (s+1) = 3s+2
The length of one side of the square is s-2, and its perimeter is 4 times that, 4(s-2) = 4s-8. The square and triangle have the same perimeter, so
... 3s+2 = 4s-8
... 10 = s . . . . . . . . add 8-3s to both sides
The length of the shorter side of the triange is 10 units.
It would take you 48.6 minutes
9X9=81 square feet
81/75=1.08
1.08X45=48.6 minutes
The answer is letter d.
The distance formula can be used to prove a quadrilateral has <span>congruent sides. In other words, the formula can be used to know if two sides are eqqual to each other.</span>
The answer is
the vector PQ has (4-1, 8-2) as components, so it is vecPQ= (3, 6)
using the definition
the distance PQ= sqrt ( 3²+6²)= sqrt(9+36)=sqrt(45)
