Answer:
m<ACD = 90
m<CDB = 126
m<EDB = 54
m<CDE = 180
Step-by-step explanation:
Well you have the right girl! *In honors geometry you can trust me!
Ok first thing...We already know
B = 54
A = 90
D = 54 (It's the Alternate interior angle of B)
C = 90
m<ACD = 90 (C = 90)
m<CDB = 126 (D = 54 ------> 180-54= 126)
m<EDB = 54 (Alternate Interior angle of B)
m<CDE = 180 (It is a straight line)
Hope this helps ya!!

Answer: 18 CM
Step-by-step explanation:
Since there are 4 sides to a rectangle, and 2 of them are lengths, we can multiply 24 by 2, which results in 48, and subtract it from the overall perimeter, which results in 36. Since the width is 2 sides, we can divide 36 by 2, which results in 18.
Answer:
SEE BELOW
Step-by-step explanation:
Since, △ABC is a right angled triangle. We can apply Pythagoras' Theorem to find the length of AB.
According to Pythagoras’ theorem, “In a right angled triangle: The square of the hypotenuse is equal to the sum of the squares of the other two sides.”
Applying Pythagoras’ theorem in △ABC, we get
AB2=AC2+BC2
⇒AB2=52+122
⇒AB2=25+144
⇒AB2=169
⇒AB=169−−−√
⇒AB=13 cm
