Write five and eight tenths in standard decimal form

the answer is 5.8

Step-by-step explanation:

divide numerator (8) by the denominator (10):

8 / 10 = 0.8

add this value to the integer part: 5 + 0.8 =

5.8 So,

5 8/10 = 5.8

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
