some students are participating in a math contest in which
each student takes one of four tests. one third of the students
take the first test, one fourth take the second test, one fifth take
the third test, and 26 students take the fourth test. how many
students are participating in the contest in total?
your answer

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
