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: 4/10 or 2/5
Step-by-step explanation:
Let us represent, the total distance travelled as:
1
Ballio's family traveled 3/10 of the distance to his aunt's house on Saturday.
Distance left to travel = 1 - 3/10
= 7/10
They traveled 4 /7 of the remaining distance on Sunday.
The fraction of the total distance to his aunt's house was traveled on Sunday is calculated as:
4/7 × Distance left to travel
= 4/7 × 7/10
= 4/10
but if i'm wrong then the answer might be 2/5
