two angles of a triangle measure 59 degrees and 63 degrees. if the longest side measures 28 cm find the length of the shortest side

26, 6487

Step-by-step explanation:

1) FInd the third angle 180-59-63= 58 degrees.

2) The longest side lies in front of the biggest angle (63degrees)  while the shortest side stretches in front of  the smallest angle (58degrees). Suppose the side that is searched is equal to x

2) Use the law of sin

28/ sin63degrees= x/ sin 58degrees

28/ 0,891= x/0/848

x= 26. 6487 cm (approximately)

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

answer is 144
