Answer:
x = 3
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle:
15x + 5 + 22x + 4 = 120 add like terms
37x + 9 = 120 subtract 9 from both sides
37x = 111 divide both side by 37
x = 3 and to find the angles replace x with 3 in given expressions
340.8 cm^2.
72+72+72+62.4+62.4=340.8cm^2.
26 feet * 12 inces per foot / 7.5 inches = 41.6, which is 41 full bracelets
