Answer:
They are similar.
Step-by-step explanation:
They both have the same ratio.
Answer:
<h2>b = 60</h2>
Step-by-step explanation:
We know: The sum of measures of angles in a triangle is equal to 180°.
Therefore we have the equation:
b° + 80° + 40° = 180° <em>combine like terms</em>
b° + 120° = 180° <em>subtract 120° from both sides</em>
b° + 120° - 120° = 180° - 120°
b° = 60°
I think it is A
Hope this help you!!!
Let us find the co ordinates of each vertex of the triangle .
Vertex A ( in firs second quadrant) = ( -5 ,3)
vertex B in third quadrant = ( -5, -5)
vertex C in fourth quadrant = ( 4, -2)
let us use distance formula AB^2 = ( -5 - 3)^2 + (-5 - -5 )^2 = 64 + 0
AB= 8
BC^2 = ( -2 - -5 )^2 + ( 4 - - 5)^2 = 9 + 81 = 90
BC = 9.48
AC^2 = ( -2 -3)^2 +( 4- -5)^2 = 25 + 81 = 106
AC= 10.29
Perimeter = sum of length of AB+ BC+ Ac = 8 + 10.29 + 9.48= 22.77
