You dont seem to try the questions you post, because you post a question every 30 minutes. Are you even trying your homework or do you want just want other people to do it for you?

3. This one is a little hard to see,  NSS....

 

The small right triangle at the bottom left  has a hypotenuse of 10 and one leg of  6

So.....the other leg  =  sqrt (10^2 - 6^2)  =  sqrt (100 - 36) = sqrt (64) = 8

 

And this right triangle and the one at the top are related in the following way ......

 

6  / 10   = h / 16      ......multiply both sides by 16......

 

16*6/ 10  = h

 

96/10  = h

 

9.6  = h

 

 

4.  Area  =  (1/2)Base x Height  =  (1/2)(13)(4)  = (1/2)(4)(13)  = 2 * 13   = 26 in^2

 

Just  as Singerforthelord found  !!!!!

 

 

cool cool cool

3)9.6  answer like Singerforthelord's comment 

4)26 in.^2

E1=bxh/2 <=> E1=10x4/2=20 <=>E1=20

E2=bxh/2 <=> E2=3x4/2=6 <=>E2=6

Efinal=e=E1+E2 =20+6=26

 

Efinal=26!!!
