Answer:
x=36
Step-by-step explanation:
2(x+9)=3(x-6)
2x+18=3x-18
X=36
I am not seeing a picture so I am going to give you the instructions to do it yourself. All you would have to do is divide the total perimeter (35 centimeters) by however many sides the polygon has. For example, if it was a pentagon, then the equation would be 35/5, which would equal 7.
Answer:
The correct answer is option B. 8,16, 20
Step-by-step explanation:
Its given that,ΔJKL ~ ΔPQR, with a scale factor of 3 : 4
The sides of ΔJKL are, 6,12,15
Let 'x', 'y', and 'z' be the sides of ΔPQR
We know that if two triangles are similar, then the ratio of corresponding sides are in same raio.
<u>To find x</u>
6/x = 3/4
x = 8
<u>To find y</u>
12/y = 3/4
y = 16
<u>To find z</u>
15/z = 3/4
z = 20
Therefore the sides of ΔPQR are 8,16 and 20
Option B. 8,16,20 is the correct answer
You square root both sides to get your answer. the picture isn't clear.
