Answer:
20
Step-by-step explanation:
The sides of the park measure 30 m and 40 m. They form the sides of a rectangle. The length of the path is along the length and width of the park, so by going along the path, the distance is
30 m + 40 m = 70 m
Going through the park, you walk in a straight line from the park to the home along a diagonal of the rectangle. That diagonal is a hypotenuse of a right triangle whose sides measure 30 m and 40 m. We use the Pythagorean theorem to find the length of the diagonal.
a^2 + b^2 = c^2
Let the legs of the right triangle be a and b. Let the hypotenuse be c.
(30 m)^2 + (40 m)^2 = c^2
900 m^2 + 1600 m^2 = c^2
c^2 = 2500 m^2
Take the square root of each side.
c = 50 m
The direct path from the school to the house is 50 m.
Difference: 70 m - 50 m = 20 m
Answer: You save 20 m.
Your answer is c. i know this because this was the exact same question i did yesterday and i got 100%
All the angles in a triangle equal 180 degrees so 128 + (5x+10) + 9x = 180
Group the like values to get 138 + 14x = 180
Subtract 138 from 180 to get 14x = 42
Divide 42 by 14 to get x = 3
Therefore x = 3
Answer:
9/20
Step-by-step explanation:
Find the common denominator:
1/5 and 1/4
1/5*4/4 = 4/20 and 1/4*5/5 = 5/20
So we can add them together now
4/20 + 5/20 = 9/20
so 9/20 of her customers order fish or chicken
Triangle has 180 degrees
1 side=180
Then 180-150= 30 degrees
30/2 (for the other two sides)= 15
So, 150 degrees, 15 degrees and 15 degrees.
So it’s probably an isosceles triangle as the two bottom angles are the same number of degrees
Hope this helps :)
