Notice the larger triangle is a right-triangle, and the small one is also a right-triangle. Also notice the "angle tickmark" on each. So both angles have a pair of angles that are equal on each.
the triangles are similar by AA.

hello there i think answer is B
Step-by-step explanation:
Answer:
21, 22, and 23
Step-by-step explanation:
Three consecutive natural numbers can be represented as n, n+1, and n+2.
The square of the smallest number would be 
and its equal to the product of the other two (n+1)(n+2).
So the equation is 
.
If n is 21 then the next numbers are 22 and 23.
The lower quartile is 60. Quartiles are the numbers in the middle of the median and lowest/highest number.
Let the width of the room be = x
Length of the room = 3x, Since it is three times as wide
Perimeter = 80m
Perimeter = 2*(L + W) = 2*(3x + x) = 80
2*(3x + x) = 80
2*(4x) = 80
8x = 80 Divide both sides by 8
x = 80/8
x = 10, But length = 3x, = 3*10 = 30
Length = 30m
