Ametal frame is constructed in the form of an isosceles trapezoid. each base angle measures 80°, the length of the base is 7 feet, and each of the nonparallel sides is 5 feet long. determine the length of a diagonal brace to the nearest whole number.

it is x equals 3   plese mark me really need it

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
