A car travels 60 miles due north then makes a turn due west. It travels 72 miles west. How far is the car from its starting poin
Harlamova29_29 [7]

Answer:

93.7 miles

Step-by-step explanation:

This problem can be represented as a right angled triangle. The distance between the final point and the starting point is the hypotenuse.

We need to find the hypotenuse. We can use Pythagoras rule:

hyp^2 = opp^2 + adj^2

where opp = opposite side to the angle considered

adj = adjacent side to the angle considered

This implies that:

x^2 = 60^2 + 72^2\\\\x^2 = 8784\\\\x = \sqrt{8784} \\\\x = 93.7 miles

The car is 93.7 miles far from its starting point.

Can someone please answer this question?
Goshia [24]

Answer:

254.34 mm²

Step-by-step explanation:

Diameter (d) = 18 mm

Radius (r) = d/2 = 18/2 = 9 mm

π = 3.14

Area of the circle

= πr²

= (3.14)(9)²

= 3.14 × 81

= 254.34 mm²

What is the equation of the line that passes through the points (−2, 1) and (1, 10)?
Viktor [21]

Answer:

3x - y = -7

Step-by-step explanation:

y = mx + b

m = deltay/deltax

m = (10 - 1)/[( 1 - (-2)]

m = 9/3 = 3

y = 3x + b

From (-2 | 1) we see that when x = -2, y = 1

Placing into the equation, in order to find b (y-intercept)

y = 3x + b

1 = 3(-2) + b

b = 7

y = 3x + 7 or 3x - y = -7

Can someone please give me the right answer.
MrRa [10]

Answer:

Y=106

X=18

Step-by-step explanation:

Both sides would have 65° because of the Alternet interior angles.

180° minus the 65° gives you 115° when you solve for X and solve for Y Use the 115° as shown in the photo below
