Tyra used 6 kilograms total to fill up all bird feeders.
Answer:32
Step-by-step explanation:
perimeter is the sum of the length of its four sides
2l plus 2w
- 8 multiply 2=6
- 12 multiply 2=24
- 24plus 8 =32
- l =8
- w=12
Each number contains a different amount than others.
Answer:
B. 75°
C. 105°
Step-by-step explanation:
We are given the figure of parallel lines with a line intersecting both of them as shown in the figure below.
B) We have, the car going south-west on King Avenue turns left onto 3rd street.
As, the lines representing 3rd street and 4th street are parallel. Their corresponding angles will be equal.
So, ∠1 = 75°
As, King Avenue intersects 3rd street, the vertical angles will be equal.
So, ∠2 = ∠1 = 75°
Thus, the angle made by the car's turning is 75°.
C) We have, the car going north-east on King Avenue turns right onto 3rd street.
As, the sum of angles on a straight line is 180°.
So, ∠2 + ∠3 = 180°
i.e. ∠3 = 180° - ∠2
i.e. ∠3 = 180° - 75°
i.e. ∠3 = 105°
Thus, the angle made by the car's turning is 105°.
