84

Step-by-step explanation:

they are all equal sides so what you'd do is 28+28+28= 84

56

Step-by-step explanation: It's an equilateral shape so all sides are equal, so then both angle UVS and UTS are congruent to each other. But since it's asking for the whole angle T you can just do 28+28=56 and that's your answer. Hope I'm right

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
