Please help thanks! Give the explanation of how we know each transformation was applied to y = 9^2 -
A) y = 9+ + 4 is a shift up because
B) y = -1) is a reflection across the x-axis because I
C) y = -1( ) is also reflection across the y-axis because
D) y = 5(9)* is a vertical stretch because​

9 x 8 divided by (5-3)=36

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
