Answer:
the triangles are similar by AA~
Step-by-step explanation:
Answer:
8%
Step-by-step explanation:
Length = 30 cm
It increases by 10 %
The increase is 30*.10 = 3
New length = old length + increase
30+3
33 cm
Width =20
It increases by 5%
The increase is 20 *.05 = 1
New width = old width + increase
=20+1
21
Old perimeter = 2(l+w) = 2(30+20) = 2(50) = 100
New perimeter = 2(l+2) = 2(33+21) =2(54) = 108
Percent increase = (new - old)/old * 100%
= (108-100)/100 * 100%
= 8/100*100%
=8%
D b they share a angle up top and a side in the middle of the triangles
38
Because a triangle adds up to 180 so if you have to angles you add them up and subtract that number from 180 and you get your answer
90 +52= 142
180-142=38
