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°
Answer:
32 miles.
Step-by-step explanation:
That would be 2/3 * 48 = 32 miles.
Answer:
DE
Step-by-step explanation:
See how DE cuts through half? We shouldn't be too accurate for the midsegment.
