The answer is C.
because 2 of the angles are congruent, and one of the sides is, so you use AAS to prove that the triangles are congruent. and then by the def. of congruence, the other sides are congruent also
Answer:
no she is not correct because 230×10^4=23,000,000
Answer:
I would say A because the real answer is 23.477
Step-by-step explanation:
Parallel have same slope
Perpendicular have opposite reciprocal slopes. Ex. 2/3 is slope of one line so the perpendicular line would have slope of -3/2.
Find slopes of these lines.
-4x-5y=-4
-4x+4 =5y
Divide by 5
Y= -4x/5 +4/5
Second line: 10x-8y=-1
10x+1=8y
Divide by 8
10x/8 +1/8 =y
Y= 5x/4 +1/8
So if you look at slope of line 1= -4/5 and line 2 it’s 5/4 so these both are perpendicular.
