Step-by-step explanation:
21/28÷7/7=3/4
Answer:
x=28/3 or 9 1/3
Step-by-step explanation:
triangle ABC is equal to triangle ADE by HL. you can solve this by setting up a proportion so for the sides its CB/ED=AB/AD. then just plug in the side lengths, cross multiply and youre done
7/13=x/8+x
56+7x=13x
56=6x
56/6=x
28/3=x

Hello! 59.2 is our answer
This is because for all the triangles we do 5.4 x 4 = 21.6 then I divide by 2 cause thats the formula when doing triangles so I get 10.8 and sense all the triangle sides our the same I do 10.8 x 4 and get 43.2 then for the bottom side I just have to do 4 x 4 cause thats the formula and get 16 then I add these up so 43.2 + 16 = 59.2 and We get our answer 59.2 Hope this helps!
