Three friends met for a book club at a coffee shop, each friend ordered a cup of coffee and two donuts. the total of the order was $22.00

a. if a cup of coffee is $3.25, then write a diagram to solve for the cost of the donut

3( 3.25 + x ) = 21.75

b. whats the donuts cost?

Step-by-step explanation:

a.

See attached diagram.

b.

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
