Ken had the following problem on a quiz: Two sides of a triangle have lengths of 8 feet and 11 feet. If the triangle’s perimeter is 28 feet, what is the length of the third side? Ken solved the problem as shown below. P = a + b + c. 28 = 8 + 11 + c. 28 = 19 + c. 47 = c. Which statement about Ken’s work is true? Ken substituted into the formula incorrectly. Ken added incorrectly when combining like terms. Ken added 19 to both sides of the equation rather than subtracting 19. Ken solved the equation correctly.

x = 23.78

step-by-step explanation:

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.

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
