Answer:
angles are 48°, 48°, 84°
Step-by-step explanation:
ratio of angles = 4 : 4 : 7 = 4x : 4x : 7x ( x is a multiplier )
the sum of the 3 angles = 180 , then
4x + 4x + 7x = 180 , that is
15x = 180 ( divide both sides by 15 )
x = 12
the student made the error of assuming x = 12 was the size of the 2 equal angles.
the correct angles are
4x = 4 × 12 = 48°
4x = 4 × 12 = 48°
7x = 7 × 12 = 84°
All the fractions are rational, all the nonrepeating decimals are rational, all the repeating decimal are irrational, all the negative numbers are integers, and all the positive whole numbers are whole numbers. Zero is an integer, and find the square roots of those numbers and put them into one of the above categories.
