Answer: 102.9 m

Step-by-step explanation:

First, use Pythagorean to find the length of AC

AB² + AD² = AC²

50² + 80² = AC²

2500 + 6400 = AC²

8900 = AC²

94.34 = AC

Next, subtract 15 (the diameter of the circle) from AC to find the length of the straight line.

94.34 - 15 = 79.34

Next, find the circumference of the circle

C = πd

C = 15π

They are only walking around 1/2 of the circle so divide it by 2.

(1/2)C = (15/2)π

≈ 23.56

Add the straight line (79.34) and the half circumference (23.56) to find the total distance traveled.

79.34 + 23.56 = 102.9

Which triangles can have two sides of the same lenghth

alisha [4.7K]

An isosceles triangle is a triangle with 2 congruent sides. The congruent sides are called legs and the third side is called the base. So if 2 sides of a triangle have the same length, then we say that the triangle is isosceles.

Determine which system of equation has (-3,19) and (4,-23) as a solution?

grandymaker [24]

Answer:

y=6x+1

Step-by-step explanation:

First you must find the slope of the two points...

$\frac{4--3}{-23-19}$ which then would equal 6

Then you take the slope and put into point-slope form

(y-y1)=m(x-x1)...take one of the points that is given and plug it into this formula.

so I used (-3,19).

(y-19)=6(x--3)

I would then get y-19=6x+18

Add 19 to both sides and you will get y=6x+1
