Step-by-step explanation:
1.(2,3)
2.No
3.1st quadrant
4.5
5.Yes
6.Quadrant-4
7.(2,-3)
4( 40 - 30)
subtract 30 from 40 is expressed as 40 - 30
then multiply by 4 is expressed as 4 × (40 - 30) or 4(40 - 30) = 40
Answer:
∠ A = 82°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
A is an exterior angle of the triangle, then
∠ A = 49° + 33° = 82°
Answer:
7.1 miles
Step-by-step explanation:
From the park to the library is a diagonal line. We can use pythagorean theorem.
Change in y - 7
Change in x - 1
7^2 + 1^2 = x^2
(x is the distance between the library and park)
49 + 1 = x^2
50 = x^2
That's around 7.
