Answer:
The ratio of the perimeter of ABCD to JKLM is;
b. 3/5
Step-by-step explanation:
Given that ABCD ~ JKLM, where;
DC and ML are corresponding sides
AD and JM are corresponding sides
AB and JK are corresponding sides
Therefore;
DC/ML = AD/JM = AB/JK
Plugging in the values of the variables gives;
9/15 = z/10 = x/12
∴ z = 10×9/15 = 6
x = 12×9/15 = 7.2
9/15 = 6/y
y = 6 ×15/9 = 10
The perimeter of the quadrilateral ABCD = AB + BC + DC + AD
∴ The perimeter of the quadrilateral ABCD = 6 + 6 + 9 + 7.2 = 28.2
The perimeter of the quadrilateral JKLM = JK + JM + ML + LK
∴ The perimeter of the quadrilateral JKLM = 12 + 10 + 15 + 10 = 47
The ratio of the perimeter of ABCD to JKLM = 28.2/47 =0.6 = 3/5.
Step-by-step explanation:
I'm pretty sure that the answer is B 81.5%
Answer:
- <u>Domain</u> : -1 ≤ x ≤ 3
- <u>Range</u> : 6 ≤ y ≤ 27
Step-by-step explanation:
The domain is the set of possible x-values.
The range is the set of possible y-values.
<u>Domain</u> : -1 ≤ x ≤ 3
<u>Range</u> : 6 ≤ y ≤ 27
Answer:
Step-by-step explanation:
acute ks little angles
obtuse is big angles
in a riangle it adds up to 180
