Answer:
3.6cm
Step-by-step explanation:
Given data
We are given that the dimension of the photo is
Height= 15cm
Width= 9cm
That is
15cm height will make 9cm width
hence 6cm height will make x widht
cross multiply
9*6= 15*x
54= 15x
x= 54/15
x= 3.6cm
Hence the width will be 3.6cm
We Cannot conclude that triangles DEF and LNM are similar if DF = 8 and LM = 4.
<u>Solution:</u>
Given that for two triangle DEF and LNM, DE = 8 and LM = 4.
To say that two triangles are similar the provided information is not complete.
Two triangles DEF and LNM , will be similar if there corresponding sides are in ratio which means
But we have only information of
But do not have any information regarding two remaining ratios that are
Hence cannot conclude that triangles DEF and LNM similar if DF = 8 and LM = 4
Answer:
If you have one of the interior angles already there for you then the alternate interior angle would be the exact same
Step-by-step explanation: Alternate interior angles theorem
1. You want to distribute the equation like this: 8+(2)(x)+(2)(−6)+x—> 8+2x+-12+x.
2. Combine like terms to this equation.
8+2x+-12+x—>(2x+x)+(8+-12)—> 3x+-4
3. You get the answer which is 3x-4.
Hoped I help :)
